Trying to bootstrap the current tree-ssa branch with GNU gmp 4.1.3 on IRIX
5.3 fails (even after fixing another problem with io/unix.c):

/vol/gcc/obj/gcc-3.5-tree-ssa-20040429/5.3-gcc-gas-gld/gcc/xgcc -B/vol/gcc/obj/gcc-3.5-tree-ssa-20040429/5.3-gcc-gas-gld/gcc/ -B/vol/gcc/share/mips-sgi-irix5.3/bin/ -B/vol/gcc/share/mips-sgi-irix5.3/lib/ -isystem /vol/gcc/share/mips-sgi-irix5.3/include -isystem /vol/gcc/share/mips-sgi-irix5.3/sys-include -DHAVE_CONFIG_H -I. -I/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran -I. -I/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/io -O2 -std=gnu99 -O2 -MT exp_c8.lo -MD -MP -MF .deps/exp_c8.Tpo -c /vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/generated/exp_c8.c   -DPIC -o .libs/exp_c8.o
/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/generated/exp_c4.c: In function `csqrtf':
/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/generated/exp_c4.c:101: warning: implicit declaration of function 'copysignf'
/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/generated/exp_c8.c:29: error: conflicting types for 'cabs'
/vol/gcc/obj/gcc-3.5-tree-ssa-20040429/5.3-gcc-gas-gld/gcc/include/math.h:300: error: previous declaration of 'cabs' was here
make[3]: *** [exp_c8.lo] Error 1

This happens because <math.h> has 

struct __cabs_s { double a,b; };
extern double	cabs(struct __cabs_s);

which conflicts with

GFC_REAL_8 cabs (GFC_COMPLEX_8 z);

This problem is likely to occur on other pre-ISO C99 systems as well
(e.g. even Tru64 UNIX V5.1B <math.h> has

extern double   cabs __(( double, double ));
), so the functions should probably be renamed wholesale to avoid such
conflicts.

Environment:
System: IRIX lynx 5.3 11091812 IP22 mips


	
host: mips-sgi-irix5.3
build: mips-sgi-irix5.3
target: mips-sgi-irix5.3
configured with: /vol/gnu/src/gcc/gcc-tree-ssa-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --with-gnu-as --with-as=/vol/gcc/lib/gas-2.14.90 --with-gnu-ld --with-ld=/vol/gcc/lib/gld-2.14.90 --disable-libmudflap --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3

How-To-Repeat:
Bootstrap the tree-ssa branch as described.
