substitution errors for variables that don't exist.
If a machine architecture dependent makefile exists, include it
to discover if libc or libc_r is being built with NetBSD syscalls
instead of FreeBSD ones.
Put a NO_QUAD thingy around the quad makefile so that 64-bit
architectures can ignore that sh*t.
In the test for MDSRCS being empty, add all MISRCS to SRCS, rather
than just ignoring them.
Define the HIDDEN_SYSCALLS macro as empty because libc doesn't have
renamed syscalls. This avoids an undefined macro error when
libc/sys/Makefile.inc goes to look though it. HIDDEN_SYSCALLS is
used by the equivalent makefile to this one in lib/libc_r to list
those syscalls that it needs to rename so that libc_r can provide
replacement functions.
(and even run). These files don't necessarily make sense for a
FreeBSD/Alpha kernel build. That will come later and these files
will be changed accordingly.
Change MACHINE references to MACHINE_ARCH.
Declare the names of the syscalls that need to be renamed to allow
for the functions that libc_r provides replacements for. This list
used to be in lib/libc/sys/Makefile.inc, but has been moved here
to keep that makefile tidy and remove the temptation for people to
add things to the list without adding a libc_r replacement function.
prototypes for the spinlock functions that will be used for thread locks.
libc will have stubs declared with weak symbols. libpthread and libc_r
will have functions that really do something.
the other syscall files are generated into. This new file is to be
included by src/lib/libc/sys/Makefile.inc to automatically pick up
syscall names.
The other file, netbsd_syscall.mk, is the hand-generated NetBSD
equivalent to be included by src/lib/libc/sys/Makefile.inc when
_NETBSD_SYSCALLS is defined during the build of libc/libc_r.
during the libc/libc_r to automatically pick up syscall names on
the assumption that default asm code needs to generated for them.
In the up-coming changes to the libc makefiles, there is the option
to provide a machine dependent asm source file which will turn off
the automatic generation of the default. There is also an option
to just stop code being generated for a syscall. In most cases,
though, the default asm code is all that is required, so this
change makes that the most convenient was to do business.

objdump all build out of the FreeBSD tree. At EDS we used to call this
a "significant emotional event".
Still using the lorder script from NetBSD until I can explain why the
is a difference in nm behaviour when the output looks the same.
Changed MACHINE to MACHINE_ARCH with the expectation that pc98 will
use elf the same as i386.
Nuked tahoe and vax 'cause the files they reference aren't in the
tree. If you want vax goto NetBSD. If you want tahoe... tough.
starting with hashes have a sub-optimal impact. This change adds
/* */ around the block comment in the header of each file to make
them friendly to cpp. Also added an Id keyword cause I like to
see revision numbers in source.
Changes to support building with _POSIX_SOURCE set to 199309L:
1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;
2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE
3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX. These show up when:
_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L
and vanish when:
_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.
4. Explain these in man 9 posix4;
5. Include _posix.h and conditionalize on new feature test.
slice number passed in by the bootblocks. This means the kernel will
not use the compatability slice to obtain the root filesystem when
booting from a sliced disk.
Use the extraction macros from reboot.h rather than stating them in full
again.
