I expect this is / was a very common problem for people porting 32-bit game code to newer compilers. I work on a fairly old codebase that forces use of x87 for a handful of code paths that don't work correctly otherwise. GCC will use default to x87 if you do an i386 compile, but will default to SSE for 64-bit builds, so you have to be careful there too.
