 This is really a gcc bug, but since the C7 seems to be a popular processor
 it might be worth it adding a workaround in the configure script.

 ccache gcc -c -pipe -march=c3 -w -fomit-frame-pointer -Wall -Wno-switch
 -O2 -fomit-frame-pointer -D_REENTRANT -DPIC -fPIC  -DMMX -Di386
 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DPREFIX=\"/usr\"
 -DLIBDIR=\"/usr/lib\" -DHAVE_AV_CONFIG_H -D_LARGEFILE_SOURCE -DQT_NO_DEBUG
 -DQT_THREAD_SUPPORT -DQT_SHARED -DQT_TABLET_SUPPORT
 -I/usr/share/qt3/mkspecs/default -I. -I.. -I../.. -I../libavutil
 -I/usr/include/qt3 -o motion_est.o motion_est.c
 motion_est_template.c: In function :
 motion_est_template.c:413: error: can't find a register in class  while
 reloading 
 make: *** [motion_est.o] Error 1

 The code builds successfully when using ./configure --tune=i686.
