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.
