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.

NEED_DECLARATION_SETRLIMIT.

Fix 980628-*.f:
* bld.h: New `pad' field and accessor macros for
ACCTER, ARRTER, and CONTER ops.

ffebld_new_conter_with_orig): Initialize `pad' field
to zero.
* com.c (ffecom_transform_common_): Include initial
padding (aka modulo aka offset) in size calculation.
Copy initial padding value into FFE initialization expression
so the GBE transformation of that expression includes it.
Make array low bound 0 instead of 1, for consistency.
(ffecom_transform_equiv_): Include initial
padding (aka modulo aka offset) in size calculation.
Copy initial padding value into FFE initialization expression
so the GBE transformation of that expression includes it.
Make array low bound 0 instead of 1, for consistency.
(ffecom_expr_, case FFEBLD_opACCTER): Delete unused `size'
variable.
Track destination offset separately, allowing for
initial padding.
Don't bother setting initial PURPOSE offset if zero.
Include initial padding in size calculation.
(ffecom_expr_, case FFEBLD_opARRTER): Allow for
initial padding.
Include initial padding in size calculation.
Make array low bound 0 instead of 1, for consistency.
(ffecom_finish_global_): Make array low bound 0 instead
of 1, for consistency.
(ffecom_notify_init_storage): Copy `pad' field from old
ACCTER to new ARRTER.
(ffecom_notify_init_symbol): Ditto.
* data.c (ffedata_gather_): Initialize `pad' field in new
ARRTER to 0.
(ffedata_value_): Ditto.
* equiv.c (ffeequiv_layout_local_): When lowering start
of equiv area, extend lowering to maintain needed alignment.
* target.c (ffetarget_align): Handle negative offset correctly.
* global.c (ffeglobal_pad_common): Warn about non-zero
padding only the first time its seen.
If new padding larger than old, update old.
(ffeglobal_save_common): Use correct type for size throughout.
* global.h: Use correct type for size throughout.
(ffeglobal_common_pad): New macro.
(ffeglobal_pad): Delete this unused and broken macro.

* gansidecl.h (ATTRIBUTE_UNUSED): Use __unused__ not `unused'.
Don't define NULL here. Also, remove all vestiges of autoconf
based checks for bcmp/bcopy/bzero/index/rindex.
* system.h: Immediately after including stdio.h, check for and if
necessary provide a default definition of NULL.
From-SVN: r20814
* choose-temp.c (make_temp_file): Accept new argument for the
file suffix to use. Allocate space for it and add it to the
template.

for the length of the suffix. Update template struture checks
to handle optinal suffix.
* collect2.c (make_temp_file): Update prototype.
(main): Put proper suffixes on temporary files.
* gcc.c (make_temp_file): Update prototype.
(do_spec_1): Put proper suffixes on temporary files.
Should fix irix build problems.
From-SVN: r20812
* Makefile.in (fix-header): Don't needlessly depend on cpperror.o.
* alias.c (CHECK_ALIAS_SETS_FOR_CONSISTENCY): Cast expansion to
void since it is evaluated in a comma list.
* mips.h (ASM_GENERATE_INTERNAL_LABEL): Always sprintf `NUM'
argument as a long and cast `NUM' to long to ensure it is of the
proper width. Wrap macro arguments in parens when they appear in
the expansion.
* sol2.h (ASM_GENERATE_INTERNAL_LABEL): Likewise.
* sparc.h (ASM_GENERATE_INTERNAL_LABEL): Likewise.
(ASM_DECLARE_RESULT): Fix fprintf format specifier to match

temporary files.
* collect2.c (choose_temp_base): Delete declaration.
(make_temp_file): Declare.
(temp_filename_length, temp_filename): Delete.
(main): Use make_temp_file to get temporary files. Use --lang-c

defined.
(choose_temp_base): Only provide prototype if MKTEMP_EACH_FILE is
