------- Additional Comments From neil at gcc dot gnu dot org 2004-12-06 02:26 ------- Eric - can you try your testcase on GCC sources as of around the beginning of August 2003?
This is when I completely rewrote the whole file lookup mechanism, and contrary to Zack's claims it did work 100% correctly, to the best of my knowledge, and would always get links, both hard and soft, correct with #pragma once correct no matter how contorted or renamed the file was. Then only issue in that code was the -remap bug that has since been fixed. However, since that date, various people have hacked at the code who probably didn't understand it. Zack did various "optimizations" and Apple added a bunch of stuff for obfuscated include file lookup and line number stuff. I think it is very likely it was broken along the way. If it was broken back around 5th August 2003 I will look into this, as it was my new code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15167
