Ports tree cvsupped on Oct 2 2000,
FreeBSD 5.0-CURRENT (not relevant)

>Description:

Due to the fact, that FreeBSD fputs does not return exact number of
bytes written, wrong value for 'tailerofset' is getting written into
the cross-reference file. That makes it impossible to reuse index file
when running cscope under cbrowser control, for instance. Cbrowser 
runs cscope with the command which looks like:

 cscope -dl -f cscope.out

where -d instructs cscope not to rebuild index file and assume it
is up-to-date. While trying to reopen pre-existing data file
cscope seeks at incorrect offset and then fails with an error 
message.

>How-To-Repeat:

Run cscope with above command line and watch it fail.
	
>Fix:
 Add attached file to the patches directory.
