Hello,
When gcc 4.5.0 is used, compiling mcp55_early_setup_car.c fails:
$ make
which: svnversion: unknown command
which: git: unknown command
GEN build.h
CC romstage.inc
cc1.exe: warnings being treated as errors

This is the only failure from abuild with gcc 4.5.0. Should we play
along (at the expense of a few extra bytes of code generation)? If so:
