Bootstrap failure on Mac OS Yosemite (10.10)

[<Paul_Koning at Dell dot com>]

I would bug this but bugz says to report things under âbootstrapâ only if they are long lived failures, and I donât know if this is.

Just tried to build on my Mac OS 10.10 system, plain native build.  It fails in libgcc2 due to stdio.h not found.  A cross-build from the same source tree (pdp11 target) works fine, though.

Here is the config, and the failure:

$ head config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.64.  Invocation command line was

  $ ../gcc/configure --prefix=/usr/local/gcc5 --enable-languages=c,c++,objc,fortran --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --with-isl=/usr/local --disable-bootstrap
