I did a build of a GCC cross-compiler for Windows, based on cygwin, that is suitable for homebrew GameCube development (as many demo-writers use it).

UPDATE:

"WinterMute has made a build of GCC based on MinGW, which is more "advanced" than mine (faster, and with some extra architecture files).

I recommend that you use his build instead of this one (it is for the moment only available for Windows). I'll update soon my Linux build to make it as compatible as possible with his build.

The current version is release 1, featuring the following things :

• GCC version 3.3
• binutils version 2.14
• newlib version 1.11.0. newlib is a replacement for glibc (the GNU C library) which is more compact and portable.

No more available for download.

NOTICE: Some people reported problems while using floats for instance. You need to find then a proper crt0.s performing FPU initialization. If you can't find one, just use -msoft-float GCC option. This problem exists on both release 0 and release 1.
