It's been a while, but I remember that indeed, it was not possible to
not pass $CC to gnulib; I made that suggestion before actually trying (I
thought it was going to be possible at the time).

FWIW, I agree with Gary's approach here.  We discussed this internally
and it's just too much work (and not a good use of Gary's time, IMHO) to
update our gnulib copy and fix this error.  Unfortunately, we will have
to address this at a later moment.

Thanks,
