Hello Lance!
Hello All!

I can but answer to your second problm, see below...

I'll be looking at this later... Just a thought: what's your shell?

Also, MPFR must reebuild its autoconf "database" to be able to build
successfully, maybe this is a problem on your machine? Can you check
the autoconf version you have installed, please?

As a third hint, did you enable OVERIDE_CONFIG_GUESS_SUB in your
.config? If so, can you try without, please?

Yes. This Makefile rule has changed between gcc-4.2 and 4.3, it's now
called libgcc.mvars instead. crosstool-NG trunk has support for building
with at least gcc-4.3.1 (4.3.0 is untested, 4.3.2 will come a bit later,
when I have time to rebase the patchset and test).

So there is currently no way to build gcc-4.3 with the crosstool-NG 1.2
branch, because it has no support to do so (and never will). Can you try
the svn trunk and report back, please?

Regards,
Yann E. MORIN.
