According to Gerry Dubois:
[...] Right, I'm using the 2.8.1 gcc source tree to compile against. I'm using gcc 2.7.2.1 to compile the cross compiler and gpc. Do you mean to imply I need to use a gcc-2.8.1 native compiler to compile the gpc source?
No. gcc-2.7.2.1 should work fine. The *source* must be 2.8.x or EGCS.
