Re: ping: updating Fortran support for f9x?

[Philippe Trottier]

Few ideas to consider...

	The detection of GNU fortran is done by passing this code to the 
compiler
with the extention .F

      program main
#ifndef __GNUC__
       choke me
#endif

      end

The problem here is that cpp is going to do the preprocess here and 
since cpp is setting __GNU__ this works. even if the compiler is in my 
case from Absoft.

	Then Absoft f77 and f95 will require f95 -V valid_source.f95 to return 
the version number ... so is f77, so the version check is also not 
working.
maybe add a case with -V and -v with

program main
end


	Some compiler behaves a bit differently when called with different 
options, should the previous test use the AC_FC_SRCEXT ? making this 
before the compiler check ?

Yours,
Philippe
