4.1 (branches/csl/sourcerygxx-4_1, which has a soft-fp backport, so using
the non-macro-expanded version of fmsub from the 4.2 patch). I will be
working on getting E500 working with long double as well (unfortunately
E500 support has got somewhat bitrotten in GCC, so sharing fixes between
4.1/4.2/4.3 there will be more difficult).
