I was planning to put them up on the OpenWatcom wiki sometime but haven't got around to it yet. A bit more testing is probably still required – so far all I've attempted is my Win32 hello world/floppy imager program.

Also can you give me a pointer on building the libs (or libc at a minimum?!)

THANKS!!!!!

You just have to do a full build using the standard configuration (the alpha, mips & ppc cross-compilers are created by default) and then build the libraries by hand in the right order (thats the hard bit). Part way through building the libraries you have to switch your compiler over to the one you're building so that later libraries can use the ones you built earlier.

I couldn't get the alpha-hosted compiler built however. Apparently the alpha code-generator is not quite complete enough to build itself. cfold.c was where it fell over for me. I was told the cause is missing support for unsigned long long <-> double conversions in the Alpha code generator.
