But I bet that's not the cause of the gcc-build-missing-stdlib/unistd
error.  I'm getting that same error while building STABLE
on a Red Hat 7.2 / glibc 2.2.4 environment
(with the RH cc/gcc replaced with gcc 2.95.3).

And it's true, stdlib.h and unistd.h don't appear to be under
the .../i386-pc-linux-gnu/include tree.  Is it a build-order problem,
where something else should have put them there before building libgcc2?

(Could I just take gcc out of all the dependency lists, and build lnx-bbc
with the gcc I already have installed?)
