[patch] Fix some errors building with clang++ trunk.

Hi!
Here is patch for squid3 trunk that fixes a couple of compile errors with clang++ trunk.
The hack in src/ChunkedCodingParser.cc gets rid of a warning that complains about a empty if statement.
There is still an issue on FreeBSD where strtoll ends up undefined, I still have no idea what is going on there.
