-------------------------+-------------------------------------------------
A build failure occurred for me in gf2x. The sse-2 test yielded
{{{
checking whether gcc -std=gnu99 can compile and run sse-2 code... yes
}}}
while if should yield
{{{
checking whether gcc -std=gnu99 can compile and run sse-2 code... requires
-msse2
}}}
Recent revisions in gf2x svn have a stricter test that yields the right
result for me.
Here is the log:
