Hello!

When I use Apple's llvm-gcc-4.2 (effectively powerpc-apple-darwin9- 
llvm-gcc-4.2) on Mac OS X 10.5.8 (Leopard) and compile GNU Emacs  
(sources from last 24 h) with these flags (with or without '-mcpu=7450  
-mtune=7450')

	CFLAGS='-g -Wno-pointer-sign -pipe -fPIC -Os' CPPFLAGS='' LDFLAGS=''
	CFLAGS='-g -Wno-pointer-sign -pipe -fPIC -Oz' CPPFLAGS='' LDFLAGS=''
	CFLAGS='-g -Wno-pointer-sign -pipe -fPIC -mstring -Os' CPPFLAGS=''  
LDFLAGS=''
	CFLAGS='-g -Wno-pointer-sign -pipe -fPIC -mstring -Oz' CPPFLAGS=''  
LDFLAGS=''

the resulting bootstrap-emacs crashes:

Compilation with optimisation level of -O[1-4] or Apple's -fast  
produces a working bootstrap-emacs, see below:

 66+ 73+ 76+ 76+ 71+ 65+ 84+ 69+ 83 = 663

 and add 3 because he's Bill Gates the third.
