This change introduced a really stupid bug:
date: 2004/08/09 03:14:11; author: amodra; state: Exp; lines: +64 -40
I converted a for() loop with continue statements to do .. while()
resulting in a loop that never exits if any of the continues are taken.
gcc mainline uses --gc-sections building libstdc++.so, and hits the
* elf64-ppc.c (ppc64_elf_gc_mark_hook): Don't hang forever in loop.
