yup, it does. There's macros for fetching the Float and making a  
double and vice versa of course. If they have set the floating point  
library up the same as for RISC OS you could steal the versions from  
the RISCOS platform tree.

Reminds me of the fun of getting things going on the NetWinder; gcc  
2.95 (etc) combined with the NW floating point emulator and/or  
library was terrible. It wasn't any  better a while later when we got  
VW running (well, trotting) on it.
