You can use the second argument to AC_PROG_FC to supply a preferred
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
for specifying files with an extension different from ".f", say ".f95".

I guess to be absolutely sure you might still need a compile test
after that.

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
require.
