The cscope on my RH7.0 box didn't take -k!
[root@mjftest linux-2.4.5]# ls -l cscope.files
-rw-r--r-- 1 root root 105530 May 30 17:58 cscope.files
[root@mjftest linux-2.4.5]# cscope -b -k -I include
cscope: unknown option: -k
Usage: cscope [-bcCdelLqTuUV] [-f file] [-F file] [-i file] [-I dir] [-s dir]
[-p number] [-P path] [-[0-8] pattern] [source files]
[root@mjftest linux-2.4.5]# which cscope
/usr/bin/cscope
[root@mjftest linux-2.4.5]# rpm -qf /usr/bin/cscope
cscope-13.0-6
weird, as man cscope documents -k's existence

I didn't see a way to add >>'ing the file to cscope.files without greping
for it's entrance there already. So I've left the find ... method of
creating cscope.files.
cscope.out is now built by a shell command which does the checking
against the age of the files in cscope.files

Backout the old patch and try this one.
