Update of /cvs/ghostscript/gs/lib
In directory casper2:/tmp/cvs-serv5155/lib

Modified Files:
	gs_cidtt.ps 
Log Message:
Handle CIDCount value of 65536 which might be seen with Identity CMap.
Fix for customer 562.

DETAILS:

while a multiple string approach had been previously implemented to allow
CIDCount > 32767, with 65536 a 'rangecheck in --string-- would result
when trying to create a string of 65538 bytes (32769 * 2). I chose a
arbitrary break point of 22000 CID's so that three strings would be
enough for 66000 total.
