Problem: Cscope is limited to 8 connections.
Solution: Allocated the connection array to handle any number of
connections. (Dominique Pelle)

The DJGPP-built version from http://cscope.sourceforge.net is known to not
work with Vim.

! There are a couple of hard-coded limitations:
!
! 1. The maximum number of cscope connections allowed is 8. Do you
! really need more?
!
! 2. Doing a |:tjump| when |:cstag| searches the tag files is not
! configurable (e.g., you can't do a tselect instead).
