--- Comment #18 from Iain Sandoe <iains at gcc dot gnu.org> ---
I needed two small additions to build (c-family+Ada+fortran+lto)
** Go and D not tested.

======
I fixed up host-darwin.c in the same way as you did for host-linux (and
disabled some of the extra checks I've got in place at the moment).
======
It looks like it adds around 10M to the largest libstdc++ case for x86_64
(151=>161Mb) so not too bad (6.6%).
1. C and C++ pch.exp seem OK
2. libstdc++ seems OK (some of the tests will use the PCH).
3. I have one failing ObjC test...
(possibly a missing or incorrectly specified GTY(()) - will investigate when I
have a chance).
FAIL: objc.dg/pch/interface-1.m -fnext-runtime -Wno-objc-root-class -O0 -g -I.
-Dwith_PCH (internal compiler error)
FAIL: objc.dg/pch/interface-1.m -fnext-runtime -Wno-objc-root-class -O0 -g -I.
-Dwith_PCH (test for excess errors)
Excess errors:
<built-in>: internal compiler error: tree check: expected identifier_node, have
error_mark in private_lookup_attribute, at attribs.c:1971
