gcc6809 - GNU C Compiler for the Motorola 6809 processor - Google Project Hosting

GCC for the 6809. This shouldn't be terribly surprising given that GCC supports 8-bit-like models of the AVR; it'd be nice if it did more of these!

www.gccupc.org

UPC appears to be roughly to C as OpenMP is to Fortran, but with support for distributed computation. (That is, it's a way of doing C-like computation with pointers and shared data across multiple machines. Whether this is a good idea I'm not entirely convinced, but it's always nice to see better compiler support for parallel programming.)
