Request to drop daft GNU extension

I'm in favour of dropping it, but I would really like to see the C99
version as a replacement, not an ongoing support for the GNU macro
varargs feature. If possible, the preprocessor should detect that a
certain expansion has a different meaning under GNU C and C99, issue a
warning, and use the C99 meaning. There should be an option to restore
the GNU C meaning.

In C99, this would be written as

#define eprintf(format, ...) fprintf (stderr, format __VA_ARGS__)

Right?
