* configure.in: new flags --with-ld and --with-as, equivalent
to setting LD and AS environment variables. Test whether
specified arguments are GNU commands, and report them with
checking messages. Use the specified AS for configure
tests too.
* configure: ditto
* acconfig.h: add DEFAULT_ASSEMBLER and DEFAULT_LINKER
* config.in: ditto
* gcc.c (find_a_file): when looking for `as' and `ld', return
the DEFAULT program if it exists
* collect2.c (main): use DEFAULT_LINKER if it exists
* gcc.c (find_a_file): the test for existence of a full
pathname was reversed

sys_siglist (like Solaris 2.7.)
Add support for strsignal, for platforms which have it but don't have
sys_siglist (like Solaris 2.7.)
* acconfig.h (NEED_DECLARATION_STRSIGNAL): Provide a stub.
* collect2.c: Don't declare `sys_siglist' here.
(my_strsignal): Prototype and define new function. Use it in
place of `sys_siglist' hacks.
* mips_tfile.c: Likewise.
* configure.in (AC_CHECK_FUNCS): Check for strsignal.
(GCC_NEED_DECLARATIONS): Likewise.
* system.h (strsignal): Prototype it, if necessary.

SImode is subsection -1 works, else use DImode.
(ASM_OUTPUT_ADDR_VEC_START, ASM_OUTPUT_ADDR_VEC_END): Define if
subsection -1 works.
* config/sparc/sparc.c (sparc_output_addr_vec,

both string.h and strings.h together.
* aclocal.m4 (GCC_HEADER_STRING): New macro to detect if it is
safe to include both string.h and strings.h together.
(GCC_NEED_DECLARATION): Test STRING_WITH_STRINGS when deciding
which headers to search for function declarations. Continue to
prefer string.h over strings.h when both are not acceptable.
* acconfig.h (STRING_WITH_STRINGS): Add stub.
* configure.in: Call GCC_HEADER_STRING.
* system.h: Test STRING_WITH_STRINGS when deciding which headers
to include. Continue to prefer string.h over strings.h when both
are not acceptable.

* configure.in: Check if the assembler supports ".balign" and
".p2align" and define HAVE_GAS_BALIGN_AND_P2ALIGN appropriately.
* acconfig.h (HAVE_GAS_BALIGN_AND_P2ALIGN): New tag.
* i386/gas.h (ASM_OUTPUT_ALIGN): If the assembler has support for
".balign" then use it.

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.
* mips-tfile.c: Include machmode.h to get HOST_PTR_PRINTF.
* Makefile.in (mips-tfile.o): Depend on machmode.h.

Add the ability to GCC_NEED_DECLARATION{S} for looking in arbitrary
header files when searching for function declarations. Use this
functionality to check for getrlimit/setrlimit.
* aclocal.m4 (GCC_NEED_DECLARATION): Accept an optional second
argument, which is typically preprocessor code used to draw in
additional header files when looking for a function declaration.
(GCC_NEED_DECLARATIONS): Likewise.
* configure.in (GCC_NEED_DECLARATIONS): Add checks for getrlimit
and setrlimit, search for them in sys/resource.h.
* acconfig.h: Add stubs for NEED_DECLARATION_GETRLIMIT and
NEED_DECLARATION_SETRLIMIT.
* system.h: Prototype getrlimit/setrlimit if necessary.

explicitly extern.
