And this is caused by the following lines in /usr/include/math.h
# ifdef _PA_RISC
# define _FPCLASSIFY(x)
(_IS32(x)?_Fpclassifyf(x)>>1:_Fpclassify(x)>>1)
extern int _Fpclassify(double);
extern int _Fpclassifyf(float);
# ifndef _DISALLOW_MASKING_MACROS
# define fabsf(x) ((float)fabs((double)(float)(x)))
# endif
# else /* __IA64__ */
