This has been posted to the GCC-Bugzilla as:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30915
There it was marked as INVALID, because the source of the problem was
determined as the Gentoo multilib setup.

In the GCC-Bug there is a possible patch, but I can't see that patch being
included in gcc, it looks like it would make much more sense in the gentoo
patchset.

I also tried to find out more why this breaks, here is what I noticed:
It breaks, because fixincludes from gcc thinks the gentoo stdio.h is broken and
needs fixing. But that fix is a rather harmless wrapper, that should normaly
just be ignored. But: This wrapper prevents stdio.h from being included twice,
and that is just what will happen with the failing .c file.
I modified the "fixed" stdio.h to output a warning each time it is included and
it shows the following output:

The when the normal gcc build includes stdio.h a second time it will be skipped
because of the fixinclude-fix and so the definitions of ::fpos_t etc. will be
missing in one namespace.

So I am opening this bug to ask the toolchain maintainer, if the fix from
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30915 (or something similar that
prevents fixincludes from touching the gentoo-multilib-stdio.h) can be included
in the gcc-4.3-ebuilds, or if I should file a bug in the gcc bugzilla that they
fix the wrapper that fixinclude inserts.

no idea why Jakub is unable to properly sort bugs

------- Comment #2 From Jonathan Adamczewski 2007-11-06 23:24:28 0000 ------- 
I've been seeing this bug with some crossdev builds.

------- Comment #3 From Torsten Kaiser 2007-12-22 16:33:01 0000 ------- 
Since around october I'm no longer seeing this bug on native builds. (I did not
try any crosscompiles)

Instead is later failed when building the precompiled header stdc++.h.
It seems to generate borken definitions for the builtin constants __DBL_MAX__,
__DBL_DENORM_MIN__ and __LDBL_MAX__.
I did not report this, as the system I was trying to build the GCC-4.3 was
using -ffast-math and that looked related.
But after not even getting this fixed by rebuilding glibc, gmp and mpfr with
different gccs I finally tried this on my stable amd64 system, where I never
used -ffast-math. The error happend there too, so this doesn't seemed to relate
to this (bad) flag.

error output from the stable amd64 system:

Whats interessting is, that some of the first stages build correctly:

(Yes, gcc really puts a ½ into this number constant. Thats the "stray '\275'"
that created the above error.)

This also looks gentoo related, as the only thing I found like this is Bug
33992 from the gcc bugzilla and that is also a gentoo system.

Patch: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33992#c10
(Changes -O2 to -O1 in toolchain.eclass, I have not tested this myself, as I
did not want to mess with this global eclass...)

------- Comment #4 From Torsten Kaiser 2007-12-22 19:38:45 0000 ------- 
Addendum:
Because of a bug/feature in the flag-rewriting logic it is not necessary to
patch toolchain.eclass.
The rewrite "replace-flags -O? -O2" does not match -O which is identical to
-O1. So changing -O3 to -O in make.conf has the same effect as the patch.

Result: same error as in the initial report. So the O2-optimizer-bug only hid
the gentoo multilib bug, that bug is still here.

The still broken crosscompiles probably didn't hit this, because they can't use
'profiledbootstrap' and the other bug seems to break only(?) in the "use
profile"-stage. (see toolchain.eclass, gcc_do_make() )

------- Comment #5 From Ryan Hill 2008-02-09 21:26:55 0000 ------- 
that's a completely different bug.  this one is about the multilib patch.

------- Comment #6 From Ben de Groot 2008-03-17 19:48:51 0000 ------- 
As 4.3.0 is now in the tree, I thought I might test it, but I also run into
this problem. Same error as in the original report above.

Why is this bug marked as FIXED? Just look at the number of dupes recently and
it is clear it OBVIOUSLY IS NOT. I ran into this _exact_ same build error
today, as posted last September by Torsten.

What is the fix for this issue? I know there is a patch for GCC that supposedly
fixes this but it has *not* hit the portage tree, so what is going on?

This is NOT fixed in glibc-2.7-r2, as I have that version emerged and upgrades
from 4.2.4 to 4.3.1 are still broken on ~amd64-multilib!

From reading this problem seems possibly related to this:

I compiled GCC 4.3.1 fine yesterday. I did an emerge --sync. After that when I
went to update I noticed that GCC 4.3.1 wanted to pull in glibc 2.8 which. With
that glibc installed, it builds fine. Try it out and let us know.

Built fine for me, too; apparently glibc 2.08 fixes it.  142 minutes total
(glibc+gcc) on a dual AMD64, Ouch!  Now if GCC would only support a parallel
build...

------- Comment #31 From Lars 2009-11-04 23:05:11 0000 ------- 
hm, i FIXED this by patching
/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/include/g++-v4/cstdio

#include <bits/c++config.h>
#include <cstddef>
-#include <stdio.h>
+#include "/usr/include/stdio.h"

#ifndef _GLIBCXX_CSTDIO
#define _GLIBCXX_CSTDIO 1

which gave me *A LOT* of warnings like /usr/include/stdio.h(283): warning:
attribute "__warn_unused_result__" ignored

but it compiles...
