Honestly, I find that hard to believe.
Me too!
One or the other is needed. If you need both, I think you're the only
person in the world who needs that.
Not bloody likely right? I am looking into that and I think the real
issue is that the versions wanted in the source tree must be the same as
the stuff dragging in by the script kicker download_prerequisites :
https://gcc.gnu.org/install/prerequisites.html
The in-tree build is only supported with the GMP version that
download_prerequisites installs.
However what do I know? There is another page that says do a bootstrap4
for extra spice and flavour in your result. That doesn't fly.

No stage4 result but whatever :\ we didn't want that anyways ?
Good, there should only be three stages.
I gather that now. Maybe the page that says "bootstrap4" could have a
line like "we don't know if this works" or words to that effect. :-\

Which version of mpc have you got in the GCC source tree, and how did
you add it there?
Whoa ... hold on a sec. I generally never use the little magic script
download_prerequisites. I had better check that :
hydra# head ./contrib/download_prerequisites
#! /bin/sh
#! -*- coding:utf-8; mode:shell-script; -*-
# Download some prerequisites needed by GCC.
# Run this from the top level of the GCC source tree and the GCC build
will do
# the right thing. Run it with the `--help` option for more information.

Sure. Right. Let's just see :
hydra# ./contrib/download_prerequisites --help
wget: not found
usage: download_prerequisites [OPTION...]
Downloads some prerequisites needed by GCC. Run this from the top level
of the
GCC source tree and the GCC build will do the right thing.
The following options are available:
--directory=DIR download and unpack packages into DIR instead of '.'
--force download again overwriting existing packages
--no-force do not download existing packages again (default)
--isl download ISL, needed for Graphite loop optimizations
(default)
--graphite same as --isl
--no-isl don't download ISL
--no-graphite same as --no-isl
--verify verify package integrity after download (default)
--no-verify don't verify package integrity
--sha512 use SHA512 checksum to verify package integrity (default)
--md5 use MD5 checksum to verify package integrity
--help show this text and exit
--version show version information and exit

Okay so it needs 'wget'. Fine. Easy to fix that.

That is precisely what I have in every machine where I try this process.
Unless the configure process goes looking for the left over tar files?
I must have made a mistake somewhere.

Let me dig around a bit and see what is going on.
What does config.log (in the build dir) say before it fails? It should
tell you where it found mpc.h and which version it found.
I deleted the failed build dir(s) to save on a bit of space.
I will repeat the experiment. Once more with feeling.
Oh also .. closed this bug thanks to great help!
stage2 failure due to .... stuff
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88633
OKay ... I will try the configure script with and without running the
download_prerequisites goodness.
