As discussed in D36764, these all assume 80-bit floats, and therefore are only useful on x86 (and ancient 68ks)--and, in fact, the tests for these functions are disabled for everything but x86. I have left these #ifs in for now, but will remove them after this patch gets submitted (and add comments about them needing 80-bit floats). Otherwise, powerpc builds will be broken.
