I have revisited now the emu387.cc and found, that there are
the fnsave and frstor instructions are supported.

Additionally I tried to debug a small test program which
uses FPU instructions with fsdb. I had set outside fsdb

SET I387=no

so (I think) that the emilator was loaded and I had no
problems.
