Ans cpu_sse. Yes, we've discussed the issue before I wrote the patch, and 
concluded that the number of affected programs is minimal. The changes will 
also be very small. We could perhaps document this - have a list of API 
changes in betweem 3.x and 4.0, (which will be referenced by just about 
every doc that comes with Allegro ;) so the user can change his program 
accordingly.

Well some things, such as writting to those variables, will be a bit tricky.

Otherwise, we can use

#define cpu_mmx (cpu_capabilities & CPU_MMX)
