Revision 1.3 of usr.bin/global/gctags/ctags.c changed the copyright string
to be read only. An interesting bit of cruft further down in the file
writes to the now const data. Compiler warnings and run-time bus errors
follow:
The change:

The compiler warning:
cc -g -O -I/usr/src/usr.bin/global/gctags -DGTAGS -DBUGFIX -DMODIFY -DYACC
-c /usr/src/usr.bin/global/gctags/ctags.c
/usr/src/usr.bin/global/gctags/ctags.c: In function `main':
/usr/src/usr.bin/global/gctags/ctags.c:112: warning: assignment of
read-only location
The bus error
Program received signal SIGBUS, Bus error.
main (argc=3, argv=0xefbfd758) at
/usr/src/usr.bin/global/gctags/ctags.c:112
112 copyright[0] = copyright[0]; /* to satisfy compiler */
(gdb)
FIX: IMHO since we are maintaining this on a vendor branch we should just
remove the silly line 112 and the #ifdef LINT that surrounds it.
