[Bug bootstrap/24688] New: sco_math fixincl breaks math.h


I'm trying to bootstrap gcc-3.4.3 on HP-UX 11.23/IA-64. I'm bootstrapping with
the HP C compiler. The system has patch PHSS_33351 installed. The tail of
/usr/include/math.h:
   inline int sqr(int __x) {return(__x*__x);}
   inline double sqr(double __x) {return(__x*__x);}
#  ifndef _STDLIB_INCLUDED
     inline int abs(int __d) { return (__d>0)?__d:-__d; }
#  endif /* _STDLIB_INCLUDED */
   inline double abs(double __d) { return fabs(__d); }
   inline double pow(double __d,int __expon) { return pow(__d,(double)__expon);
}
#endif

#endif /* _MATH_INCLUDED */

The tail of math.h after fixinc:
   inline double sqr(double __x) {return(__x*__x);}
#  ifndef _STDLIB_INCLUDED
     inline int abs(int __d) { return (__d>0)?__d:-__d; }
#  endif /* _STDLIB_INCLUDED */
#ifndef __GNUC__
   inline double abs(double __d) { return fabs(__d); }
   inline double pow(double __d,int __expon) { return pow(__d,(double)__expon);
}
#endif

#endif /* _MATH_INCLUDED */

Looking at inclhack.def, sco_math seems to be the cause of this. I replaced
'inline double abs' in select of sco_math with 'inline double _abs' and the
#ifndef __GNUC__ wasn't included in the new math.h.
