The current version from git is release 20101114; it uses the Texas
Instruments headers, so there are a lot of other changes. It should have
been possible to make this work with 20101006 and the legacy headers, but
you're better off with the new stuff anyway.
The #if 1 hack went into the TI version with the following. It's likely you
ran into this problem, and that the patch needs to be in the legacy version
too. I'll try to remember to add it.

commit 8edaf13d98f40c40fd6a8caebdbea2847ac875fe
Author: Peter A. Bigot <[email protected]>

Temporarily unconditionally define macros for CPUX.
gcc does not support -mmcu tags for 55x2 and similar chips, and the
iomacros.h header is included before the functional presence
preprocessor
symbol is available. For now, disable the check and make the sfra*
macros
always available. In the future we want mcu options that support
generic
CPUX chips; at that point it's reasonable to require the user to provide
those flag, or to have another header that automatically defines them
based
on the specific chip symbol.
