Sorry if I wasn't precise enough.

1. My hardware is a G4 (i.e. 32bit ppc cpu, no 64bit support) running  
Mac OS X 10.4.6, reinstalled in the last month from scratch, i.e.  
blank hard disk, formatted HFSX+J.
2. I have Xcode 2.2 installed.
3. I am using a special user portage, group portage, to experiment  
with portage-prefix. Homedir is /Volumes/portage, again HFSX+J.
4. I am using portage-alt-prefix-20060406.
5. I have no special environment, i.e. SHELL=/bin/bash, TERM=xterm- 
color, PATH=/bin:/sbin:/usr/bin:/usr/sbin, DEFAULT_PATH etc. unset.
6. I try to bootstrap portage using the command
$ ./portage-alt-prefix/scripts/bootstrap-prefix.sh /Volumes/portage/ 
prefix
This script first fetches and compiles odcctools, then gcc-apple-5247.
7. In particular, this script does not pass --disable-multilib to gcc  
configure.
8. The following make boostrap-lean fails as posted before. As I  
suspected, I was not the only one experiencing this bug, even though  
the reference in my last mail is to mainline-gnu-gcc.
9. The gcc-people don't seem to consider this a bug, I filed one with  
apple, though, to see what they think.
10. In the meantime: What's the correct way to --disable-multilib,  
i.e. a profile ppc32 and a profile ppc64, hardcoded in bootstrap or a  
bootstrap commandline option --disable-multilibs? What are multilibs,  
i.e. does this mean the compiler executable will take advantage of  
64bit hardware even if compiled on 32bit hardware or just that the  
compiler is able to generate fat binaries? Do we want multilibs in  
portage or do we want to give the user a choice? It's Gentoo after  
all...
