I did some poking around with pcc -S and it looked like %%ax was only
appearing in the context of the fnstsw instruction, which in pcc's
source only occurs once, in line 329 of arch/i386/local2.c:

expand(p, 0, "\tfnstsw %%ax\n");

My assembly is *really* basic, so I don't know what that means, but
hopefully it's relevant?
