Thanks.  Was this based on CheckCCompilerFlag from that version too?

Agreed.  Do you have example failure messages from any compilers?

Local testing of GNU Fortran 4.9 shows that bad flags are rejected with
an error.  Do we need the pattern matches for any Fortran compilers?

Certainly the "but not for C" message will not show up from a
Fortran compiler.
