Fortran dialect.  I don't think that will guarantee a compiler that
speaks this dialect though.  You will also need to use AC_FC_SRCEXT

I guess then you should ask someone who uses Fortran 95 (maybe somebody
is reading here), or simply look into the code that you're trying to
build: whatever Fortran 95 feature that code uses is one that you
