[杭杰]

  When I cross compile the latest mplayer source for xscale (with iwmmxt),
I have errors as following:
  arm-softfloat-linux-gnu-gcc -I../libavcodec -I../libavformat -Wdisabled-optimization -Wno-pointer-sign -Wdeclaration-after-statement -I. -I.. -I../libavutil -Wall -Wno-switch -Wpointer-arith -Wredundant-decls -O4   -pipe -ffast-math -fomit-frame-pointer    -c -o native/RTjpegN.o native/RTjpegN.c

  It seems that both MMX & iWMMXt option are turned on. When I use a compiler without iWMMXt, it compiles OK.

  my compiler configuration is:
