Actually no.

(pause to cringe before answering embarrassing questions he hoped never to be asked).

The -msoft-float flag requires the gcc float emulation library to be compiled 'statically'. Apple does not currently do this thus you will end up with lots of undefined symbols. The other side effect of this flag is that compiler wont emit floating point commands with it's inline structure copies.

Does this mean software (ie integer math) emulation of fp stuff? ie, if I do:

double x = y + 5.6;

Will it work? (ie will I get the correct result, even if its totally slow)?
