GCC Makefile variable `XCFLAGS'. Something like the following sed (ONLY for

Please forgive me if I'm missing something here, but I'm not quite sure
I'm seeing how this could work.
# grep -c "XCFLAGS" Makefile.in

I ran the above on a freshly unpacked gcc-4.0.1 (I did that because I
didn't any difference in the Makefile produced with or without your sed,
so I went to see if the sed actually changed anything.)
In any case, what would be the difference between what you're trying to
accomplish with a sed and the results of something like:
make CFLAGS="-g -O2 -fomit-frame-pointer"
I noticed that in the resultant Makefile, we have CFLAGS = -g -O2 and
that it gets referenced in various places. I started (but didn't finish)
a build using the above command and it does indeed use those flags.
