Subject: Re:  [gfortran] libgfortran doesn't compile on Tru64 UNIX

Bootstrap on alpha-dec-osf5.1b doesn't succeed either, but this time it's a
different failure:

/vol/gnu/src/gcc/gcc-dist/libgfortran/intrinsics/associated.c:26: error: parse error before numeric constant

This happens because <sys/types.h> has

#define TRUE 1
#define FALSE 0

so we get

enum { 0 = 0, 1 = 1 };

But even with the obvious patch below, I run into another error:

/vol/gnu/src/gcc/gcc-dist/libgfortran/generated/exp_c4.c:29: error: conflicting types for 'cabsf'
/vol/gcc/obj/gcc-3.5.0-20040517/5.1b-gcc/gcc/include/math.h:315: error: previous declaration of 'cabsf' was here
make[3]: *** [exp_c4.lo] Error 1

I.e.

GFC_REAL_4 cabsf (GFC_COMPLEX_4 z); 

vs.

extern float cabsf ( float, float );

This is similar to PR libfortran/15266, which isn't fixed yet, either.

	* intrinsics/associated.c: Renamed FALSE, TRUE to GFC_FALSE,
	GFC_TRUE.
