Arjen, I need a quick response to the question at the end... Alan

That's wonderful news, Andrew.

I have reviewed the various pieces of documentation for the Intel, Absoft,
Portland Group, and gfortran compilers.  They all claim to be fortran 95
compilers. Also, Absoft, Portland Group (at least its current release), and
gfortran accept the .f, .f90, and .f95 suffix.  (Fortran 95 code can appear
with all suffixes. The .f suffix simply means the code is in fixed format
and the .f90 or .f95 suffixes mean it is in free format.) Despite being
fortran 95 capable, the Intel compiler only accepts .f and .f90 suffixes
(unless you use the impossible [from the autotools point of view]
-TfFILENAME option to tell the compiler to not worry about suffixes for the
file called FILENAME.)

So it appears the the current Intel compiler (unless you use the impossible
-Tf option) and the old release of the Portland Group compiler do not accept
the .f95 extension, but everything else I have looked at does.  Also, it
appears that all these fortran 95 compilers accept the .f90 extension.  (I
have just checked that with gfortran in bindings/f95, and Andrew reports
good results for the Intel compiler and old release of the Portland Group
compiler.)

To allow our users to use the Intel compiler and the old Portland Group
compiler, I am leaning toward leaving our f95 directory names intact (to
indicate we really do have a fortran 95 interface), but renaming all the
present *.f95 files in bindings/f95 and examples/f95 to *.f90 as suggested
by Andrew.

Arjen, you have a lot more fortran 95 experience than me.  Also, you are the
original instigator of the fortran 95 interface.  Thus, I think it is your
call.  What do you think is the best thing to do?
