This is supposed to turn (some) warnings into hard errors, right?  My
PPC Linux box seems rather unimpressed:

gcc  -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
-D_ISOC9X_SOURCE -I"/home/diego/src/ffmpeg/ffmpeg" -I"/home/diego/src/ffmpeg/ffmpeg"
-I"/home/diego/src/ffmpeg/ffmpeg"/libavutil -fomit-frame-pointer
-maltivec -mabi=altivec -g -Wdeclaration-after-statement -Wall
-Wno-switch -Wdisabled-optimization -Wpointer-arith -Wredundant-decls
-Wno-pointer-sign -Wcast-qual -Werror=declaration-after-statement
-Werror=pointer-arith -O3  -c -o postprocess.o postprocess.c

There are many more of those warnings and eventually compilation
succeeds.
