  13  * From discussions it was chosen to push compat code as far down as possible.
  14  * That means we can have a seperate compat for most
  15  *  compatability and portability hacks and resolutions.
  16  *
  17  * This file is meant to collate all those hacks files together and
  18  * provide a simple include for them in the core squid headers
  19  * (presently squid.h)
  20  *
  21  * It should not be included directly in any of the squid sources.
  22  * If your code requires any symbols from here you should be importing
  23  * squid.h at the top line of your .cc file.
