Rechecked with gcc-3.2.3 and 3.3 CVS 20030429

The libquicktime package fails on the ia64 autobuilder with an internal
compiler error, as shown below.  A previous version of libquicktime 
successfully compiled with an unknown (but probably older) version of gcc.
[I don't know the version that correctly compiled libquicktime]

gcc -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../../include/quicktime -O3 -funroll-all-loops -fomit-frame-pointer -finline-functions -W -Wall -Wno-unused -Winline -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -c mot_est_mb.c -MT mot_est_mb.lo -MD -MP -MF .deps/mot_est_mb.TPlo  -fPIC -DPIC -o .libs/mot_est_mb.lo
mot_est_mb.c: In function `MBMotionEstimation':
mot_est_mb.c:614: Internal compiler error in copy_to_mode_reg, at explow.c:725
Please submit a full bug report,

Same with reducing the options to -O0
