Hi,

FWIW, the 20060415 mainline (4.2) snapshot bootstrapped for me, using
odcctools-20060413 (odcctools-590.36od13).  This machine is a dual G5
(ppc970) using OS X 10.3.9, and Apple's gcc-3.3 (build 1640).

However, before building, I patched the following 2 files:
In gcc/config/darwin.h:
at: #define LINK_COMMAND_SPEC :
replace:	/usr/bin/libtool
with:		/path/to/odcctools/bin/libtool

In libstdc++-v3/scripts/make_exports.pl (for OS X 10.3 only):
replace:	nm -P
with:		/path/to/odcctools/bin/nm -P
(probably not necessary if this nm is already found first in path)

Configure command (your paths may vary):
../configure --prefix=/Users/fang/local/gcc-4.2 \
        --program-suffix=-4.2 \
        --disable-nls \
        --with-gmp=/sw \
        --with-mpfr=/sw \
        --infodir='${prefix}/share/info' \
        --with-included-gettext \
        --host=powerpc-apple-darwin`uname -r|cut -f1 -d.` \
        `if test ! -f /usr/lib/libSystemStubs.a ; then echo -n "--with-as=/Users/fang/lib/odcctools/bin/as --with-ld=/Users/fang/lib/odcctools/bin/ld" ; fi`

The default languages enabled are c,c++,java,fortran,objc according to
configure.

I also made sure all the odcctools came first in my path, a blunder I
made earlier.  GMP 4.1.4 and MPFR are installed in /sw.

It might not hurt to add a few hints to
http://gcc.gnu.org/install/specific.html#powerpc-x-darwin
since I (and several other PR reporters) also had trouble bootstrapping
4.2 a while back.

Many thanks to all who help maintain the powerpc-apple-darwin port.
