Comment:

 Should be fixed on trunk by r14686, but I've not tested yet.

 We're actually now using {{{-mfpmath=sse -msse2 -mtune=generic
 -march=pentium4}}} which assumes a Pentium 4.  SSE2 added double precision
 FP instructions, and we use double a lot, and the last two mean that we'll
 generate code which will work on a Pentium 4, but is optimised to run fast
 on modern CPUs.
