[theora] Problem compiling libtheora-1.1alpha2 on OpenBSD/amd64

[Vladimir Támara Patiño]

Good morning in the Lord

I could compile libtheora-1.1alpha2 on OpenBSD i386 however trying to
compile on OpenBSD amd64 with GCC 3.3.5 and with GCC 4.2:

cc -DHAVE_CONFIG_H -I.  -I/usr/ports/multimedia/libtheora/w-libtheora-1.1alpha2/libtheora-1.1alpha2/lib -I..  -I/usr/ports/multimedia/libtheora/w-libtheora-1.1alpha2/libtheora-1.1alpha2/include -I/usr/local/include -Wall -Wno-parentheses -fforce-addr -fomit-frame-pointer -finline-functions -funroll-loops -O2 -pipe -MT mmxencfrag.lo -MD -MP -MF .deps/mmxencfrag.Tpo -c /usr/ports/multimedia/libtheora/w-libtheora-1.1alpha2/libtheora-1.1alpha2/lib/enc/x86/mmxencfrag.c -fPIC -DPIC -o .libs/mmxencfrag.o

Any clue?
