instead of the locked counterparts by defining macros.
* config.in: Regenerated.
From-SVN: r24175
* configure.in: Call AC_FUNC_VFORK.
* collect2.c: Define VFORK_STRING as a printable string for
error messages (either "vfork" or "fork".) If HAVE_VFORK_H is
defined, include vfork.h. If VMS is defined, define vfork()
appropriately. Remove vfork check on USG, we're using autoconf.
(collect_execute): Pass VFORK_STRING to fatal_perror instead of
checking locally what string to pass.
(scan_prog_file): Likewise.
(scan_libraries): Likewise.

specified arguments are GNU commands, and report them with
checking messages. Use the specified AS for configure
tests too.

pathname was reversed
From-SVN: r22629

to include. Continue to prefer string.h over strings.h when both
are not acceptable.
From-SVN: r22204
Redesign GCC_FUNC_PRINTF_PTR so that it doesn't define HOST_PTR_PRINTF
directly. Instead, autoconf will only determine whether "%p" works and
its up to machmode.h to base its definition of HOST_PTR_PRINTF on that.
This ensures that machmode.h is always included to get the definition of
HOST_PTR_PRINTF for lossy hosts or cross compiles where "%p" is not
found.
* aclocal.m4 (GCC_FUNC_PRINTF_PTR): Don't define HOST_PTR_PRINTF.
Instead, define a new macro HAVE_PRINTF_PTR which only signifies
whether we have the %p format specifier or not.
* acconfig.h: Delete stub for HOST_PTR_PRINTF, add HAVE_PRINTF_PTR.
* machmode.h (HOST_PTR_PRINTF): When determining the definition,
check HAVE_PRINTF_PTR to see whether "%p" is okay.

* Makefile.in (mips-tfile.o): Depend on machmode.h.
From-SVN: r20953

header files when searching for function declarations. Use this

argument, which is typically preprocessor code used to draw in
additional header files when looking for a function declaration.

and setrlimit, search for them in sys/resource.h.

* configure.in: Collapse multiple calls to AC_CHECK_FUNCS into one
call. Collapse multiple calls to GCC_NEED_DECLARATION into one
call to GCC_NEED_DECLARATIONS (new macro.) Check if we need
declarations for bcopy, bcmp and bzero.
* acconfig.h: Add stubs for bcopy, bcmp and bzero declarations.
* gansidecl.h: If we have bcopy but don't declare it, then do so.
