Hi all,

Attached patch was triggered by PR 52313 
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52313), and tries to improve error 
messages for module reading. It fixes one spelling of "GFORTRAN" --> "GNU 
Fortran" and improves the error reporting of old *unversioned* format from:

> Parse error when checking module version for file 'blah.mod' opened at (1)


> Cannot read module file 'blah.mod' opened at (1), because it was created by 
> an older version of GNU Fortran

In addition, I looked at the message emitted for old, *versioned* format:

> Wrong module version '6' (expected '9') for file 'blah.mod' opened at (1)

I think this message is not actually clearer to the user than the new one, so I 
substituted the new message to it too. That means we don't present the version 
strings (which are currently numbers) to the user, and it also seems better to 
me: those are for internal use anyway, and not documented. They're useful only 
to us, and they're written in the module file anyway.

So, bootstrapped and regtested on x86_64-apple-darwin11, OK for trunk?
