The game was larger than the 64K address space. I remove the intro and replace part of libc. Now I can play startrek in YAZE-AG.
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".
