Oh, yes, I guess you should incorporate your changes to config.guess and
config.log into libtool's copy of those files.  Libtool imports those
files just as GCC does.  (And no, I do not know how you named your
toolchain; please fill in the correct values yourself).

For the next failure you are likely to encounter, please provide a bit
more information: excerpts from config.log are usually helpful.

OK.

OK.

As far as I know, libtool patches are ok for GCC as soon as we apply
them to our CVS tree.  I have already done that, because your patches
were very simple and it was virtually impossible for them to do harm
(please gently ignore my forward-porting brown paper bag..)

So from their standpoint, the patches should be acceptable.

You may be able to do better, though: we may be able to find out more
about your system by running libtool's test suite on it, and thus
improve libtool's RDOS support.

AFAIK that is how it works.

For what you are trying to achieve, the differences are not significant.
A bit of work, maybe, but not much.
