Update of /cvsroot/swig/SWIG/Examples/php4/cpointer
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv12012/cpointer

Added Files:
	BUILD.sh example.c example.i runme.php4 
Log Message:
Updated examples to function correctly with new php4 module.  Added
some supplemental examples for cpointer, overloading and references using
proxies.
