 So I don't know if you want to update the comment that specifically
 states F77 and F90 or not...

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,
Ralf

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.

Thanks Ralf!

If it matters, as I understand it, the name pgfortran is meant to  
symbolize that the compiler now supports things beyond Fortran 90 --  
it supports Fortran 95 and some Fortran 03 (and beyond?) features.  So  
I don't know if you want to update the comment that specifically

Hi Jeff,

 Could Libtool be adjusted now to look for the pgfortran name first
 for all Fortran variants, and if not found, fall back to the old
 names?  That would seem to give flexibility for the future.

That name doesn't seem to be problematic, can't see any other use of  
it

out there.  I'm pushing this patch.

Thanks,
Ralf

Recognize `pgfortran' as Portland compiler.

* libltdl/m4/libtool.m4 (_LT_COMPILER_PIC, _LT_LINKER_SHLIBS):
Accept `pgfortran*' too.
