/*
 * From discussions it was chosen to push compat code as far down as possible.
 * That means we can have a separate compat for most
 *  compatibility and portability hacks and resolutions.
 *
 * This file is meant to collate all those hacks files together and
 * provide a simple include for them in the core squid headers
 * (presently squid.h)
 *
 * It should not be included directly in any of the squid sources.
 * If your code requires any symbols from here you should be importing
 * squid.h at the top line of your .cc file.
