Lemme put it this way.  I am willing to write the patch to change GCC
if and only if I do not have to write configure macros.  And configure
macros must be written unless we can prove that "cs/je", "rep/stosl",
etc. are acceptable by all the assemblers that people care about,
since time immemorial.

So you get three choices:

1) Make GAS accept cs;je and do the right thing.
2) Prove that cs/je, rep/stosl, etc are acceptable to all i386
   assemblers since time immemorial.
3) Write the GCC patch yourself.  And I will not review it.

And yes, those are in order of decreasing preference.
