Hi

I am trying to compile GCC from the latest development code and I stumble upon
this error. I attach all the details and can reproduce it if needed. I am
primarily interested in making gccgo work.

I don't think so (maybe you picked the wrong PR number, and meant PR63622 ?). I
had this patch in my tree already, when I reported this ICE.

Anyway, I'm bootstrapping a fresh compiler, including your commit, so I'll be
able to tell soon for sure.

--- Comment #12 from howarth at bromo dot med.uc.edu ---
With the commits of https://gcc.gnu.org/ml/gcc-cvs/2014-11/msg00357.html and
https://gcc.gnu.org/ml/gcc-cvs/2014-11/msg00370.html, the darwin bootstrap
should be fully restored on darwin13 and earlier.

The patch to fix the configure scripts, generated from the broken libtool.m4,
remains to be applied to fix the darwin14 bootstrap.
