Could you do me a favor?  Using a simple example (like the one I think
you sent earlier), compile with the `-v' (`--verbose') option, such
that the symptom (unterminated-constant diagnostic generated by cpp)
is evident.

Send the output of all the above, plus the sample file (e.g. `cat' it
into the output or whatever), to egcs-bugs.

I'd like to see it myself, and others should see it.  What I'm
looking for right now is whether `-traditional' gets passed by the
g77/gcc driver to cpp when compiling Fortran.  It's *supposed* to.
And, maybe it is, but a subsequent option (or some such thing)
disables the behavior, or maybe the wrong version of cpp gets
invoked, or something.

(I assume you're aware that the docs already explain that files ending
in .F and .FPP automatically are preprocessed.  This mechanism *should*
include passing `-traditional' to cpp.)
