I got pooler's code to compile for PPC OSX as well (he made the code work for big endian systems now, thanks pooler!), but it fails on some systems I tested on. I'm going to recompile on Monday with a different machine and see how it goes. If I get a good binary, I'll post that as well.
ssvb's code would likely work better for PPC, but I'm having more serious problems compiling it. There are missing header files, etc. I'm sure it's because OSX 10.4 is so old. (I don't have any machines running 10.5, so I haven't tested ssvb's code there)
Anyway, I'll post a PPC binary if I can get it to work well. If I ever get ssvb's code to compile, I'll post that as well.
