Hi,
So, I eventually managed to install slackware (only packages for passing the
host reqs, running jhalfs, and running the slackware package management
system. The key point (I think) is that I haven't installed the package
"gmp-5.0.5-x86_64-1", and that it does not prevent gcc to run, simply because
libgmp.so.10.0.5 is also included in elflibs (actually, it is in one of Hazel
Russmann's posts).
And I get exactly the same error:

Adding --with-gmp-include=$(pwd)gmp --with-gmp-lib=$pwd/gmp/.libs *does not
help*.
Actually, I wonder whether it would not be cleaner to use host gmp, mpfr and
mpc completely, for building gcc pass1. Those libraries are installed anyway
with recent gcc. The only requirement would be that the headers be installed
too.
Well, I have just read the thread "GCC build first pass: mpc build looks for
libgmp.la in the wrong place" to the end (should have done that before, I
know!). Basically, the build only fails when libmpfr.la is on the host and
libgmp.la is not. But if any is on the host, the build system uses paths on
the host. I'll try to reproduce this on Debian.
