Edit startrek.c so I can compile it with gcc and OpenBSD libc.

Browse source 
Rename our getline() to get_line() to prevent a conflict with POSIX
getline() declared in stdio.h.

Remove dangerous call to gets().  OpenBSD does not have gets(), C99
deprecated it and C11 removed it.

Also change spelling "sheild" to "shield".
