PellesC supports the ARM family of processor only, so it will not work with your hardware. The free eVC++ compiler from Microsoft covers every processor, but is a big download (300MB) and a steeper learning curve.
If you want to compile on your PocketPC, then I have tried PocketGCC, but to be honest, it is no more than a toy. It is so difficult and slow to compile anything that it is not for serious use. There are versions available for ARM processors, but I don’t recall if they ever did a sh3 build.
After that you have the option of interpreters. The only one I liked was DialectPro (Freeware), but I think there is a Small C available also.
Have fun
