I've installed binutils and gcc46 via macport (it took 2 days to compile 
it and all prerequisites).  That didn't help, because macports binutils 
doesn't provide the gnu assembler (because binutils gas can't generate 
Mach-O object files).  So, I've run into the same assembly error.

Next I'll be building static libs, that should avoid triggering the 
incompatible macro.
