04124133c0 freeze softfloat-fpu-ver3 branhc and open it for free testing 
I will continue the development in new softfloat-fpu-ver4 branch
Current version already implements ALL FPU instructions except
   FSIN, FCOS, FSINCOS, FPTAN, FPATAN, FYL2XP1, F2XM1, FYL2X
I think it solved all currently reported bugs and feature requests
related to FPU code.
Please write your own test programms and test the implemntation in all ways you can.
Thanks,
Stanislav
