Re: Fun with Squid2 and Clang

Hm.

I'm trying 3.HEAD now, but it's giving me some trouble; analysis
starts up fine, but when it gets to doing cf_gen_defines, it switches
over to using g++ and doesn't switch back; see below.

cf_gen didn't cause any problems for squid2; is there something new
and weird in the build process here?
