This switches the /usr/bin/cpp shell script cpp wrapper to tradcpp. As the script sets -traditional by default anything calling this script has been getting traditional semantics.
gcc3 and gcc4 have a builtin preprocessor that is used by default that can be disabled with -no-integrated-cpp in addition to the standalone cpp binary. clang only has an integrated preprocessor and does not have a standalone preprocessor or the option of using one. With this change src and xenocara build fine, I'd be interested to hear how a ports build goes. I get the impression that FreeBSD is using tradcpp for all ports that require an external cpp after looking at "port is required by" on http://www.freshports.org/devel/tradcpp .
