(vfork_save::restore_pid): New method.
(vfork_save::restore_exit): New method.
* fork.cc (vfork): Save ctty, sid, pgid and restore them when returning to
"parent". Use exitval field if exiting but never created a new process.

vfork.

returning from vfork.

* include/cygwin/version.h: Bump api minor number.
* malloc.cc: #ifdef sYSTRIm for when MORECORE_CANNOT_TRIM is true.

ResumeThread.

* configure.host: Default -DMB_CAPABLE for x86-linux.
* libc/include/reent.h: Define _sbrk to take signed int argument.
* libc/include/sys/unistd.h: Ditto for _sbrk_r and sbrk.
* libc/locale/locale.c[MB_CAPABLE]: Add LC_MESSAGES support and
make locale name checking more efficient. Also allow "C-ISO-8859-1"
locale for LC_CTYPE and LC_MESSAGES.
* libc/reent/sbrkr.c: Change prototype to take ptrdiff_t.
* libc/sys/linux/brk.c: Change sbrk prototype.
* libc/sys/linux/include/time.h: Remove Cygwin stuff and
include <sys/features.h>.
(CLOCK_THREAD_CPUTIME): Renamed to CLOCK_THREAD_CPUTIME_ID.
(CLOCK_PROCESS_CPUTIME): Renamed to CLOCK_PROCESS_CPUTIME_ID.
* libc/sys/linux/sys/cdefs.h: Replace with glibc sys/cdefs.h
with a few local additions.
* libc/sys/linux/sys/features.h: New file.
* libc/sys/linux/sys/unistd.h: Change _sbrk_r and sbrk prototypes
to take signed argument.
* libc/syscalls/syssbrk.c: Change sbrk, _sbrk_r, and _sbrk
prototypes to take signed size argument.
EF_M68HC11_ABI): Define for ABI specification.
(STO_M68HC12_FAR, STO_M68HC12_INTERRUPT): Symbol flags for
linker and debugger.
(R_M68HC11_24, R_M68HC11_LO16, R_M68HC11_PAGE): New relocs.
(R_M68HC11_RL_JUMP, R_M68HC11_RL_GROUP): New reloc for linker
relaxation.
* libc/sys/linux/machine/i386/crt0.c (__bss_start,_end):
Declare as extern chars and use the address operator to
properly use values set in linker script.
* dcrt0.cc (dll_crt0_1): Just wait for signal thread to go live rather than
going through the overhead of invoking it.
* fork.cc (fork_child): Ditto.
* exceptions.cc (signal_fixup_after_fork): Call sigproc_init here.
* sigproc.cc (proc_can_be_signalled): Assume that the signal thread is live.
(sig_dispatch): Ditto.
(sig_send): Ditto.
(wait_for_sigthread): Renamed from "wait_for_me". Assume that wait_sig_inited
has been set and that this function is only called from the main thread.
* winsup.h (wait_for_sigthread): Declare new function.
* libc/stdlib/mallocr.c: Include <limits.h>.
(request2size): Change macro to do
unsigned long comparisons and avoid signed overflow.
(mALLOc): Add overflow check for the number of bytes to allocate.
(rEALLOc): Ditto.
* configure.host: Add check for --enable-newlib-io-pos-args
and define WANT_IO_POS_ARGS flag if enabled. Define
the flag by default for x86-linux configurations.
* configure.in: Add support for --enable-newlib-io-pos-args.
* libc/configure.in: Ditto.
* configure: Regenerated.
* libc/configure: Ditto.
* libc/stdio/Makefile.am: Specify -fshort-enums for compiling
vfprintf.c and vfiprintf.c.
* libc/stdio/Makefile.in: Regenerated.
* libc/stdio/vfprintf.c: Add positional argument support that
is enabled by compiling with -DWANT_IO_POS_ARGS.
