svn commit: r1211432 - /trafficserver/traffic/trunk/configure.ac

[ig...@apache.org]

Author: igalic
Date: Wed Dec  7 13:35:40 2011
New Revision: 1211432

URL: http://svn.apache.org/viewvc?rev=1211432&view=rev
Log:
Bring the possibility to build with clang.
n.b.: Right now, this does not work, because our code has long since
(v2.1.4/TS-427) parted with clang compatibility.
XXX: Why are we not checking for clang on darwin? Isn't XCode the
default.. thing? Doesn't it come with clang? How often more will I
write clang in this commit message? Questions...
