Hmm. when I try it, it gives 200.000000
This is with cgcc -m68020 -lgnu020, with or without -m68881.
cgcc is gcc 2.5.8 compiled with a little change to enable gcc's floating
point emulator (whatever that is), which got rid of some errors or
warnings (I forget) when enabling the 'long double' support.
gnu020 is MiNTlibs pl45.

So, which versions of gcc and the libs did you use?
