finite is implemented as the macro "isfinite" on hpux 11.  I believe
it's available as finite on hpux 10.

Looking at the results of the gfortran testsuite on hppa2.0w-hp-hpux11.11,
I see that hpux 11 is also missing hypotf, roundf, frexpf and scalbnf.

>From math.h, the following are not available under hpux 11.11 (_PA_RISC):

#    ifndef _PA_RISC
       extern float exp2f(float);
       extern float exp10f(float);
       extern float expm1f(float);
       extern float log1pf(float);
       extern float fmaf(float, float, float);
       extern float acoshf(float);
       extern float asinhf(float);
       extern float atanhf(float);
       extern float frexpf(float, int *);
       extern float ldexpf(float, int);
       extern float modff(float, float *);
       extern float logbf(float);
       extern float scalbnf(float, int);
       extern float scalblnf(float, long);
       extern int   ilogbf(float);
       extern float hypotf(float, float);
       extern float erff(float);
       extern float erfcf(float);
       extern float gammaf(float);
       extern float lgammaf(float);
       extern float lgammaf_r(float, int *);
       extern float tgammaf(float);
       extern float ceilf(float);
       extern float floorf(float);
       extern float nearbyintf(float);
       extern float rintf(float);
       extern float roundf(float);
       extern long  lrintf(float);
       extern long  lroundf(float);
#      if defined(__STDC_EXT__) || defined(_INCLUDE_LONGLONG)
         extern long long llrintf(float);
         extern long long llroundf(float);
#      endif
       extern float truncf(float);
       extern float nanf(const char *);
       extern float remainderf(float, float);
       extern float remquof(float, float, int *);
       extern float fdimf(float, float);
       extern float fmaxf(float, float);
       extern float fminf(float, float);
#    endif /* !PA_RISC */

Basically, the problem is hpux 11 for hppa predates C99.  I don't expect full
C99 support until the next release.  I expect the situation is worse for
hpux 10.

A similar problem applies to libstdc++:
