HEAD does not compile cleanly

Due to unclean pointer arithmetic in the chunked mempools
implementation HEAD no longer compiles cleanly.

When you develop Squid code, please make use of as many warning
options of the compiler as possible, and don't accept any warnings.

Attached you can find the script I use to compile Squid during
development. It sets most warning options of GCC-2.x that can be
applied without too many "false" warnings in the base Squid code, and
uses a less strict set when compiling the auth helpers..

To use the script you need to adjust the paths at the top of the
script.

1. prefix, the prefix under where your compiled Squid's will be
installed. (each in it's own directory).

2. srcdirs, a list of directories where you keep your Squid source
trees. The script searches this list until it finds the requested
version.

Note: The script always builds using a separate object directory, and
it assumes the sources is bootstrapped.
