floating point consistency between Blackfin and PC

we have some code running on a BF-537 using the IEEE floating point emulation library. We also want to run the same functions on the PC (we use MinGW) and get the exact same results. But unfortunately this has been very difficult so far. Using the compiler flags -mfpmath=sse -msse2 helped somewhat, but there are still differences, usually concerning the last digits. Has anybody else tried this successfully?
