Similar problem.  For irix6.5.22m we have the following definitions in 
<internal/math_core.h> included by <math.h>


/* C99: 7.12.3 floating-point classification functions. */

/* The following 18 entry points are defined in c99's libc. __generic is a builtin
 * defined in the c99 front end. */

extern int _fpclassify(double);
extern int _fpclassifyf(float);
extern int _fpclassifyl(long double);
extern int _isfinite(double);
extern int _isfinitef(float);
extern int _isfinitel(long double);
extern int _isinf(double);
extern int _isinff(float);
extern int _isinfl(long double);
extern int _isnan(double);
extern int _isnanf(float);
extern int _isnanl(long double);
extern int _isnormal(double);
extern int _isnormalf(float);
extern int _isnormall(long double);
extern int _signbit(double);
extern int _signbitf(float);
extern int _signbitl(long double);

#define fpclassify(x) __generic(x,,, _fpclassify, _fpclassifyf, _fpclassifyl,,,)(x)
#define isfinite(x)   __generic(x,,, _isfinite,   _isfinitef,   _isfinitel,,,)(x)
#define isinf(x)      __generic(x,,, _isinf,      _isinff,      _isinfl,,,)(x)
#define isnan(x)      __generic(x,,, _isnan,      _isnanf,      _isnanl,,,)(x)
