Find PHP4

This module finds if PHP4 is installed and determines where the
include files and libraries are.  It also determines what the name of
the library is.  This code sets the following variables:

::

  PHP4_INCLUDE_PATH       = path to where php.h can be found
  PHP4_EXECUTABLE         = full path to the php4 binary
