bug#1151: Building Emacs on Mac OS 10.3.9

[Alex]

I'm trying to build Emacs from CVS on my old iBook running Mac OS 10.3.9.

The last Emacs I built on this machine was GNU Emacs 22.1.1
(powerpc-apple-darwin7.9.0, Carbon Version 1.6.0) of 2007-06-05 on
Alpinobombus.local

I also tried to build Emacs 22.3 on this iBook a while ago and it
ended with the following error:
ld: /usr/lib/gcc/darwin/3.3/libgcc.a(_fixunssfdi.o) illegal reference
to symbol: ___cmpdi2 defined in indirectly referenced dynamic library
/usr/lib/libgcc_s.1.dylib

So now I'm trying Emacs from CVS:

./configure --with-ns
make bootstrap

This is where it ends:
