[gfortran,ping] support for large kinds in front-end and library

[Steve Ellcey]

I applied the patch and tried bootstrapping on IA64 HP-UX.  It failed due
to the C++ style comments in fortran/trans-intrinsic.c.  I believe this
should show up on any platform and is not HP-UX specific.  I will tweak
the file and see if I get further.
