Rewrite the Installer app on the Montauk Toolkit (Canvas + gui/mtk
widgets, theme, hover states, scrollbar) replacing the hand-rolled px_*
renderer and bespoke TrueType usage.
Add a new "Software" step: an expandable checkbox tree for optional
components (Montauk SDK with gcc/g++, binutils, tcc, lua sub-items;
Games; Office; Internet apps; Printing; experimental httpd and SDR).
Unchecked components' paths are excluded from the install copy, with a
longest-path ownership rule so e.g. sdk/tcc installs even when the rest
of the SDK is deselected. The update flow refreshes only the components
the target already has.
Add tri-state checkbox and disclosure-arrow widgets to the MTK toolkit
(anti-aliased, supersampled).
Merge tcc and lua into 0:/sdk (0:/sdk/tcc, 0:/sdk/lua) and drop 0:/lib:
update tcc config.h, lua luaconf.h, both Makefiles, the devkit clean
scope, man pages and montaukos.org notices.
Make printing optional: init skips printd when 0:/os/printd.elf is
absent.

The GCC driver relocates its install prefix from argv[0]. crt1
hardcoded argv[0] as "prog", so make_relative_prefix cwd-joined it
and computed exec prefixes relative to the current directory
(0:/users/admin/../libexec/gcc/...), and because the computed
gcc_exec_prefix is non-NULL the standard /sdk prefixes were never
searched. cc1plus was unreachable from anywhere except (by accident
of the path arithmetic) 0:/sdk/bin. sdk-diag proved the kernel and
libc layers all worked; only the driver's self-relocation was lost.
New SYS_GETEXECPATH (151) returns the absolute path the process was
spawned from (Process::name); crt1 uses it for argv[0] with a "prog"
fallback. With a real argv[0], make_relative_prefix computes
0:/sdk/bin/../libexec/gcc/ from any cwd. Native GCC relinked against
the new crt1; sdk-diag ships in the SDK as a permanent probe; the
montauk.h TCC mirror gains the wrapper (checker enforced it).

Cross-build GCC 14.2.0 with --host=x86_64-montauk: the driver, cc1,
cc1plus and collect2 now link as static Montauk ET_EXEC binaries
against the hosted libstdc++, and ship in the SDK. Together with the
native binutils, TCC and the target sysroot, MontaukOS carries a
complete self-contained C and C++ toolchain at 0:/sdk.
libc: anonymous mmap/munmap over SYS_ALLOC (GCC's page allocator
wants mmap; SYS_ALLOC memory is page-aligned by construction),
getpagesize, minimal sysconf, MB_CUR_MAX, isascii/toascii, POSIX id
typedefs (ino_t, dev_t, nlink_t, ...), struct stat fields switched to
proper POSIX types (st_size is a signed off_t now), and a
conventional _STDIO_H guard marker so GMP's FILE detection works.
Build recipe and the five host-build gotchas (bundled config.subs,
gettext removal, stdio guard sniffing, endianness cache preset,
sysroot sdk symlink) are documented in toolchain/README.md. The
devkit stages the driver as gcc.elf/g++.elf/cpp.elf, the backends in
the libexec layout the driver expects, a copy of ld where collect2
searches, and a 0:/tmp scratch dir. Ramdisk: 1604 files, 368 MB.

The cross toolchain now builds real hosted C++: std::string, vector,
unique_ptr, iostreams and exceptions all work in a plain
x86_64-montauk-g++ invocation with no special flags. This is the
library that native cc1plus will link against for the GCC self-host.
crt1 now runs .preinit_array/.init_array before main and hooks
.fini_array through atexit (main returns via exit(), so destructors
run on both exit paths). Global constructors and libgcc's eh_frame
registration both ride this. GCC is reconfigured with
--enable-initfini-array (modern arrays instead of .ctors),
--with-newlib (satisfies libstdc++'s crossconfig for unknown hosts),
--disable-wchar_t and --disable-libstdcxx-pch; the montauk gcc patch
grows a hunk keeping os/generic ctype under --with-newlib (the
Montauk libc is not newlib).
libc additions harvested by the libstdc++ build: mbtowc/wctomb,
strxfrm, strtok/strtok_r, a real vfscanf/fscanf/scanf (character-
driven with widths and l/ll; also unblocks gprof later), fgetpos/
fsetpos/setbuf/fpos_t, modf plus the C99 float math variants
(acosf..tanhf, hypot/hypotf as wrappers), FP_* classification macros,
the full POSIX errno vocabulary, complete DT_* dirent types, and
mbstate_t.
The SDK ships the real libstdc++.a (was an empty stand-in), the C++
headers at 0:/sdk/include/c++, and cxx-test.elf (global ctor, string,
vector+sort, unique_ptr, throw/catch; exits 0 on 5/5). Ramdisk sits
at 1571 files, within the 2048 table.

MontaukOS binaries could not use thread-local storage: the ELF loader
ignored PT_TLS and no FS base was ever programmed, so any %fs access
(initial-exec/local-exec TLS, e.g. libbfd's _Thread_local error state)
page faulted at address 0. This is the kernel prerequisite for
cc1plus/libstdc++ in the GCC port.
ELF loader: parse PT_TLS and build the main thread's TLS block above
the loaded image (x86-64 variant II ABI: block below the thread
pointer, TP = base + align_up(memsz, align), .tdata copied from the
template, .tbss zeroed, ABI self-pointer stored at [TP]). The
template description is kept on the process for thread spawns.
Scheduler: fsBase per thread, loaded into IA32_FS_BASE at every
dispatch site through a per-CPU cache - TLS-free processes cost one
MSR write per CPU ever, and userspace cannot desync the cache since
CR4.FSGSBASE stays off. SYS_THREAD_SPAWN gives each new thread its
own TLS block copied from the template (allocated from the process
heap; reclaimed at process teardown).
Ships tls-test.elf in the SDK (built by the devkit target): checks
.tdata values, .tbss zeroing, and the %fs:0 self-pointer, exiting
nonzero on failure. Boot-smoke verified; existing TLS-free programs
are unaffected.

0:/usr was a Unix transplant in an otherwise Montauk-native layout.
The SDK now lives at 0:/sdk/{bin,include,lib} (+ ldscripts under
0:/sdk/x86_64-montauk): Montauk-flavored, and a clean unit for a
future per-component installer tickbox. Native binutils is rebuilt
with --prefix=/sdk so ld's compiled-in search paths follow; future
ports configure with --prefix=/sdk.
Also add pathconf() with _PC_* names to the libc: now that realpath
exists, libiberty's lrealpath.c compiles its pathconf fallback path
unconditionally.
Shell command resolution and tab completion updated to 0:/sdk/bin.
Boot-verified in QEMU: setup, login, desktop on the new image with
zero usr/ remnants in the ramdisk.

The devkit target in programs/GNUmakefile stages the native binutils
(as, ld, ar, nm, objcopy, objdump, readelf, ranlib, strip, size,
strings, addr2line, c++filt, elfedit as *.elf) into the image at
0:/usr/bin, plus a target-side sysroot: libc headers, montauk/ and
Api/ SDK headers and the freestanding C++ set at 0:/usr/include, and
libc.a + crt1/crti/crtn objects (with empty libm/libstdc++ stand-ins)
at 0:/usr/lib. ld's ldscripts ship under 0:/usr/x86_64-montauk.
The /usr prefix matches the binutils configure prefix, and the kernel
already resolves driveless absolute paths against the cwd drive, so
compiled-in /usr/lib search paths work natively on drive 0.
The shell resolves commands from 0:/usr/bin (after 0:/os) and tab
completion lists it. When toolchain/native/ has not been built, the
devkit step skips cleanly and the image builds as before.

Switch all program and library Makefiles from host g++ (or the
bare-metal x86_64-elf compiler) to x86_64-montauk-g++/gcc and drop the
flags the target now owns: -nostdinc + kernel freestanding -isystem
paths, -m64/-march, -fno-PIC, -mno-red-zone, -mcmodel=small, -static,
-Wl,-m,elf_x86_64, -z max-page-size, --build-id=none. Deliberate
policy flags stay (-ffreestanding, per-app SSE, -nostdlib + link.ld).
Program builds now require the montauk toolchain and fail with a
pointer to build-montauk-toolchain.sh; lib/ and libs/ keep the host
fallback since the toolchain script bootstraps libc through it.
Userspace is also now pinned to the cross GCC instead of drifting
with the distro compiler.

A standalone Window Server app for browsing curated sets of characters
and copying them to the clipboard for pasting into other apps.
- Four sets (Latin, Punctuation, Currency, Symbols) shown as a responsive,
scrollable tile grid with category tabs, a live preview/detail footer,
and a Copy button.
- Click a tile (or use arrow keys + Enter/Space) to select and copy; a
transient toast confirms the copy. Mouse wheel scrolls; Tab cycles sets.
- Styled with the MTK theme (accent, surfaces, rounded tiles) to match the
other Montauk apps, modeled on the calculator app.
The character set is deliberately the single-byte Windows-1252 range the
system font can render (the glyph cache only holds codepoints 0-255).
Copying writes the raw byte, so glyphs render identically here and in every
other single-byte-text Montauk app (copying UTF-8 would render as mojibake).
Registered in programs/GNUmakefile and scripts/install_apps.sh alongside
calculator; menu category "Applications", icon accessories-character-map.svg.
