HP-UX 11.00 patches for 0.9.3

HP-UX 11.00 patches for 0.9.3

[gsl-discuss]

HP-UX 11.00 has isinf() and isfinite() as a macro in <math.h>. Also
replaced the OS/2 hack with something hopefully better (untested).

BTW, any plans to upgrade to autoconf 2.5x?

Thanks, I've added that with a few adjustments.  I didn't see why
AC_ARG_PROGRAM was deleted so I kept that in.

No, due to the incompatibility with perl 5.004.

Oh, oops. It's not needed. I think it was called by another macro.
Check the output of ./configure --help with and without it.
