11e6c54cfc C99: Define a NAN macro in <math.h> which evaulates to a constant expression of
a single-precision quiet NaN; only to be defined on platforms that do support
this value.

0560606383 Reuse the trick of loading 0.0 (rather than 1.0) and then modifying the
exponent.  It's a bit faster on some machines.

30dca7f7db Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d
in their respective header files).  Add PSEUDO stubs for the old versions
of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

0ffda58ae9 A new implementation of _setjmp/_longjmp that uses the T_FLUSHWIN trap.
This means the stack frame and program counter can restored directly
from the jmp_buf, eliminating the need to backtrack through frames
which does not work in all cases.

dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

efd37a7da8 Warn about references to the compatibility vfork() (i.e. the vfork() with
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.

This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.

bedc7b48df Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S
with the syscall numbers changed.

Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers).  __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns.  (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)

eb96023de7 Quick fix to repair runtime link problem with libc - "SYS_sigaltstack
undefined".  The sigaltstack structure layout didn't actually change on
the sparc, so just change the syscall name.  A better fix would probably
be to replace the direct system call with a function call to the libc
sigaltstack().

4d7e773266 A foolish consistency... gen, net, and string all get MD sources
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
