Yes, I've heard about this; my original request said:

But there is no way in hell I will ever be able to use an unpublished
compiler to build the product.  Even after 3.3.3 is released it will
take some time before we can switch to using it.  I need a shorter-term
solution.


So far my best bet seems to be to punt --with-headers and --with-lib,
then set appropriate variables on the "make" command line to get it to
do what I want.

This isn't as easy as I'd hoped (since it turns out one make variable
controls all three things I need to change: where to find the
cross-assembler, etc.; where to find the target system headers; and
where to find the target system libs--I need these to be in different
places).  But, with some trickery it seems doable.
