building -current from OS X: unknown machine mode 'libgcc_cmp_return' (etc.)
Building -current/i386 on OS X, I ran into a new problem - full details below, short description is that building in src/external/gpl3/gcc/lib/libgcc blows up with: 

        error: unknown machine mode 'libgcc_cmp_return'
        error: unknown machine mode 'libgcc_shift_count'

I'm not sure if this is related to my other build issue on OS X[1][2].
Googling the error message indicates[3] that this may be related to running some configure script with the right args, but I do not dare to go there. 

Got a clue?
