It's because Snow Leopard reports itself as "i386-apple-darwin10.0.0",  
but its compiler builds x86_64 executables by default. Since x264  
thinks it's going to be built in 32-bit, it passes "-march=i686" to the
compiler, which protests...

You can build a 64-bit x264 by running " ./configure --host=x86_64- 
darwin ", or build it 32-bit by running
" CFLAGS=-m32 LDFLAGS=-m32 ./configure " for the moment.

In the long term, "./configure" should be patched : the easiest way to  
check what gcc will output by default
is to run "echo | gcc -dM -E -c" and look whether __x86_64__ or  
__i386__ is defined.
