That comment is not all that important.  But it might be useful to test
for it in AC_PROG_FC.

OK to commit this untested patch?

Thanks,

    Add pgfortran to list of Fortran 95+ compilers.
    
    * lib/autoconf/fortran.m4 (_AC_F95_FC): Add pgfortran before
    pgf95.
    Based on report by Jeff Squyres.
