Trying to configure SDL with --disable-cpuinfo didn't help. As far as I can see, the define SDL_CPUINFO_DISABLED is set, but never checked. --disable-assembly doesn't help either, as the define SDL_ASSEMBLY_ROUTINES is not checked in SDL_cpuinfo.c. Trying to activate other assembler code (the one defined after #elif defined(__sun) && defined(__i386)) resulted in a successful compile, but the resulting library segfaults in this function.

Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).

We're not planning to fix this ourselves, though patches are welcome!
