/*
 * <sys/socket.h> for the MontaukOS git port.
 *
 * MontaukOS does have TCP -- the kernel exposes it as IPC handles through
 * montauk::socket(), not as BSD descriptors -- but nothing bridges the two
 * into the fd space that read()/write() use, and git's transports assume a
 * descriptor it can hand to a sub-process. Until that bridge exists, every
 * call here fails with ENOSYS, which surfaces as "unable to connect" from
 * `git clone git://...` rather than as a crash.
 *
 * That leaves the local transports -- init, add, commit, log, diff, and
 * clone/fetch/push against a path on disk -- which are what this port is for.
 *
 * Implementations in montauk-compat.c.
