<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>So I’m thinking in the case when I compile clang on the system from svn and will probably keep them in sync. You are right that this probably doesn’t make sense in distribution builds. However, I’m not sure this is any worse then what is already done, where some “random” paths are already compiled in (see my clang++ -v t.cc below) :-) Might even speed up clang by a few nanosecs to not have to stat those non existent directories on every run. :)<BR>
<BR>
Maybe a simpler fix for me now is to soft link all the g++ includes into /usr/local/lib/clang/1.1/include (btw should that be 2.7?) which is better then having to edit InitHeaderSearch.cpp<BR>

Thanks,<BR>

IMHO, the best solution would be to find it on "standard" paths... maybe add a "--gcc-include-path" parameter or something. What do you think?<BR>
