I managed to get a hello world app working on the Wii! but I had to do some hacking of the generated C code because the devkitPPC is missing 2 posix headers referenced in the generated C code from Jhc. The functions the code used from those headers didn't seem completely essential. Basically I set the define JHC_isPosix to 0, commented out problem code. Of-course this isn't ideal, the solution would be to implement the missing headers for devkitPPC.
