[flac-dev] PATCH for cpu.c

[Oliver Stöneberg]

Hi,

after having some discussion of the FPU/SSE behavior on the sf.net 
bug tracker as well as having some other changes we made for the 
MAME/MESS project sitting around I thought about joining this list to 
make things easier.

First one is the latest modification we had to make to compile with 
clang 3.4 x64. Here are the warnings the 1.2.1 source will give with 
it:

src/lib/libflac/libFLAC/cpu.c:90:23: error: unused variable 'FLAC__CPUINFO_IA32_CPUID_CMOV' [-Werror,-Wunused-const-variable]

                      ^
10 errors generated.

This is simply fixed by putting those unused constants into the 
proper defines. I attached a patch against git 70b078c.

Greetings
