Thank you for this information, I now have more of an insight of how it's done :) cheers James > > > > ... or you can compile them yourself using the fpc source, but that's > somewhat more complicated. > > If you want to compile for another cpu (fpc 1.0.10 supports i386 and > m68k; fpc 1.1 currently supports i386, powerpc and sparc) then you > *must* compile the compiler.
