That question on stackoverflow is about CPU support, the patch 
you replied to was about OS support. Because of the registers 
used (which must be saved and restored on a context switch), the 
OS must support a certain instruction set or the program will 
crash. AFAIK the detection of those things is unrelated.

FLAC already wasn't working on Windows 98 and older because of 
the UTF-8 implementation that was merged for flac 1.3.0, so no 
one will care I guess.
