Although I've been unsuccessful in identifying the root of the problem,
in crtstuff.c, why was this added?
+ #define IN_LIBGCC2 IN_LIBGCC2
as all non-32/64 bit targets need to lie about UNITS_PER_WORD to libgcc2
in order to coerce it into generating anything other than garbage, so it
may not be a good idea for this lie to propagate beyond libgcc2's bounds,
as it could inadvertently affect correct target header definitions.
