Hi Tony.

That's good news - I couldn't find much info on the nuts and bolts of the
complex stuff in gcc-3.4.x (Is there some manual that is up-to-date? The
gcc manuals I found are from 2002 or older).

I just tried to change a few complex declarations to _Complex on the big
machine and they even seem compatible with the normal 'complex'
declarations.

The program doesn't use sophisticated complex functions, so there's a
good possibility it'll work.

Anyway, I'll also explore the minGW way, as I would appreciate
stand-alone executables.


Thanks for the info.
John
