Update of /cvs/ghostscript/gs/src
In directory casper:/tmp/cvs-serv21022/src

Modified Files:
	gscedata.c gscedata.h gscencs.c gscencs.h 
Log Message:

Adds a procedure for testing whether a string was returned by
gs_c_glyph_name.  Allows the font copying code to share these strings,
substantially reducing the load on the garbage collector.
