Gcc will default to -std=gnu99 sooner or later, and then the C99
compliant assert will be the default.  FWIW, I'm actually against having
the function name on assert's failure message; it just makes it longer
for no good reason (if I need to know the function's name, I can read it
from the stack traceback or straight from the source when I look at it
to see why it failed).  Therefore I'm inclined to do the minimum needed
to comply with C99, which is what the patch does.

Maybe a little, but still not very good; see
http://gcc.gnu.org/gcc-3.3/c99status.html (about C99 support in general,
not the effects of -std=c99).
