As another datapoint, I recently built a 32-bit signed fixed-point library of sorts in C for flight control. This was an extremely painful process because of the problem of representing negative-zero in the integer bitfield using two's compliment. It worked, but its performance was only slightly better than the built-in support on one board, and about 10x slower than that built into gumstix boards...so the performance can vary greatly.
