What compiler are you using to build the stage 1 compiler?

It looks like the problem is that libbacktrace is picking up the header files
from the GCC you are building, not the header files from the compiler that is
doing the build.

The error shows that libbacktrace is including ../gcc/include/unwind.h, but
that file should not exist at the time that libbacktrace is built.  I assume
that it does exist, but why?

Precisely how did you run configure?

Created attachment 28399

toplevel config.log

I'm attaching the toplevel config.log.  From it I read that the compiler is
configure:4103: gcc --version >&5
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658)
(LLVM build 2336.1.00)
Copyright (C) 2007 Free Software Foundation, Inc.

The configure command was
  ../configure --enable-languages=c,c++,fortran
(my build directory is a subdirectory of the gcc directory)

I ran make in a directory with a pre-existing build, ao maybe that include file
was an old leftover.  Please don't invest any further time in this now, I'll
try a clean build first.

Ok, a clean build works.  Sorry for the noise, looks like unwind.h was a
leftover from some previous revision.

I'm opening this again, as I find the same problem again after updating my git
tree, so it's not due to some changed dependencies in the libbacktrace merge:

I could fix this by deleting all occurences of unwind.h in the build tree.  I
therefore assume that some dependencies are broken.

--- Comment #7 from Nicolai Josuttis <nico at josuttis dot de> 2012-11-01 10:14:30 UTC ---
I got the same problem when switching from revision 1191942 (Oct 1st, 2012) to
revision 193061 (Nov 1st, 2012).
The effect was that the following files existed in the build tree:
 -rw-r--r-- 1 nico None 10659 Sep 21 10:16 gcc/include/unwind.h
 lrwxrwxrwx 1 nico None    36 Oct  2 00:04 i686-pc-cygwin/libgcc/unwind.h ->
../../../src/libgcc/unwind-generic.h

After removing 
 gcc/include/unwind.h
the problem disappeared.

As you can see, my environment was:
 CygWin under Windows 7 x64
 (i686-pc-cygwin)

Config settings were:
../src/configure \
 --enable-languages=c++ \
 --disable-bootstrap \
 --prefix=/cygdrive/p/gcc/gcc$VERSION \
 --program-suffix=$VERSION \
 --with-gxx-include-dir=/cygdrive/p/gcc/gcc$VERSION-include \
 --disable-lto \
 --disable-sjlj-exceptions \
  2>&1 | tee -a ../make.log
