I'll confess I missed that FAQ entry, but it's rather pessimistic.
And it doesn't provide any direction on HOW to build without
gcc.  configure's options are not described in any detail, much
less the ability to override defaults (CC, GCC_FOR_TARGET, etc.)
with environment settings.

Runtime is not a problem.  I have that from the vendor.  I assumed
I'd have to do some source editing but I'm not afraid of that.  What
I need is some information on how to get started.  Right now to do
anything requires building gcc, which completely, utterly fails
due to the lack of target support I mentioned.

How can I just strip out the library bits and build that?

Eventually (as in much, much later), I'd like to merge some of
my work into the official sources.  I think having free libraries
that work with many compilers is an important objective.

Thanks!
