wouldn't it be better to deprecate the -V switch altogether?

I am wrong.  And it is useful thing for GCC developers really.

Confirmed.

In fact it worked with "gcc version 4.4.0 20081229 (experimental) [trunk
revision 142951] (GCC) "

I'm fine with deprecating -V - anyone care to send a patch?

No more switch -V, so FIXED. (or WONTFIX as you prefer). Use gcc-VERSION
directly, which should work every where.

--- Comment #9 from Michael Matz <matz at gcc dot gnu.org> ---
Heh.  I just had an actual user who wanted to make use of -V; because in the
build system he was working in, the compiler name 'gcc' was hardcoded
everywhere, but he could add options via environment variables, so
'gcc-VERSION'
was no option, but '-V VERSION' would have been possible, except of course,
that it isn't anymore ;-)

Well, too bad, I guess.
