When I try to compile the ld64 (97.17) linker from Apple cctools on MacOS 10.4
(arch = ppc) I get the following error:

Any idea to what it is related to?

TIA,

Looks like a problem with platform name prevents including <bits/c++config.h>.

This macports bug might help:

"llvm-gcc42: can't find bits/c++config.h on Leopard/PPC"
https://trac.macports.org/ticket/33293

You mean that the exception is triggered by the missing include file? I am
going to correct this, but there should maybe be a cleaner way out, no?
Cheers

It is no better when the missing include file is found. I get another assert:
