Doesn't work here:

gcc -DHAVE_AV_CONFIG_H -I.. -I/home/guillaume/Prgm/ffmpeg/libavutil -g 
-Wdeclaration-after-statement -Wall -Wno-switch -O3 
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_ISOC9X_SOURCE   -msse  -c 
-o i386/fft_sse.o i386/fft_sse.c
i386/fft_sse.c: Dans la fonction ?ff_imdct_calc_sse? :
