The bootstrap fails building the libstdc++ PCH file.
The system compiler is used to attempt the build and fails because it doesn't
undetstand -std=gnu++0x because it's an old compiler.

----------------
MacOSX:~/obj ed$ gcc -v
Reading specs from /usr/libexec/gcc/darwin/ppc/3.3/specs
Thread model: posix
gcc version 3.3 20030304 (Apple Computer, Inc. build 1671)
----------------

I think the stage3 g++ should be used.  I think this is a build system mistake.
I tried to hand edit the makefile with a stage3 compiler (I think) and add -B
but I couldn't get g++ to find cc1plus.

I think you'd want the stage3 compiler even if the system compiler understood
C++0X for consistency.  Also, you can't bootstrap with any g++-3* or even
g++-4.0.*.  At least not with extra flags maybe.

I was able to bootstrap on this platform as late as October 15, 2009.

My configure is
../gcc/configure --prefix=/Users/ed/bin --with-gmp=/usr/local
--with-mpfr=/usr/local --with-mpc=/usr/local --enable-decimal-float
--enable-languages=c,c++,fortran,objc,obj-c++

Thank you,

Ed

Here is the end of the build output.  I don't know if the ignored fails are
probative or not.
