Project policy now is to require C99 support, so the correct solution
for using an older compiler is to do something like
./configure CC="gcc -std=gnu99" ...
We're not going to accept patches to remove declarations-in-for-loops,
as that feature was actually one of the primary arguments for requiring
C99 in the first place. (Also, I'm pretty sure that there are already
considerably more than two such uses.)
