I fixed a problem in the i686 build recently, but the symptom was different from your: GCC itself failed to build.
Maybe it's worthing try 09 release (which will probably be announced today)

(Yes, the fix is to get rid of cbuild1 and more importantly the requirement for 32-bit builds in a prehistoric environment - it builds just fine on 64-bit present-day boxes... But I don't think we want to make that change in a respin).
The "variably modified" errors remain even after hardcoding
typedef struct { __cpu_mask __bits[16]; } cpu_set_t;
instead of relying on __CPU_SETSIZE and __NCPUBITS, and the line where it complains about alignment not being a positive power of 2 actually hardcodes an alignment of 16. Have you run into those before?
