Steven Bosscher 69d3c9a43e re PR libfortran/15960 (missing function 'finite' on HP-UX 11.11) 
PR libfortran/15960
	* configure.ac: Check for finite in libm.
	* libgfortran.h: Define isfinite macro if not defined.
	* intrinsics/c99_functions.c: Use defined(fpclassify) instead of
	HAVE_FPCLASSIFY.
	* io/write.c (write_float): Use isfinite instead of finite.
	* configure, config.h.in: Rebuilt.
