*BSD commonly means FreeBSD, OpenBSD and NetBSD, but since Apple's Darwin
has a FreeBSD userland, I also add Darwin to it. At least Darwin's
userland seems to be compatible enough to be included, despite its
internal Mach architecture.

Common *BSD files:

bsd.pa BSD specific syscall functions
bsdmacro.inc The POSIX mode_t (IS_DIR etc) and exit macro's.
bsdsysc.inc The base syscalls for *BSD system unit.
including a few that are _not_ posix, but still
required in the system unit. All routines have
a public alias.
bsdsysch.inc EXTERNAL declarations for the non-posix calls in
bsdsysc.inc (to import them into e.g. Unix)
bsdtypes.inc some non POSIX BSD types required for the
syscalls and base functions.
bsdfuncs.inc POSIX syscalls and functions that are not needed
for system.
osposix.inc The implementation of unit posix, redirects to libc
or bsdtypes.inc (via aliases)
osposixh.inc The headers of unit posix.
sysctl.pp Some basic sysctl headers, needed for implementation
of POSIX functions.
sysposix.inc BSD specific part of the implementation
i386/syscall.inc The primitives for performing syscalls
i386/syscallh.inc Headers to syscall.inc
powerpc/syscall.inc likewise for PPC.
