  Modify h323 to build against PTLib as well as the older PWLib
  
  Several changes in PTLib have occurred requiring build time detection. Changes
  accounted for include the library name change, config option change, install
  location change, and a boolean type change which is handled by ast_ptlib.h.
  Also, the sed check has been modified to properly work with autoconf >= 2.62.
