Subject: vim-patch:7.4.1866

Problem:    Invalid memory access when exiting with EXITFREE defined.
            (Dominique Pelle)
Solution:   Set "really_exiting" and skip error messages.

https://github.com/vim/vim/commit/a96732150cda2f242133228579b05437a39b8daa

This fails to build, due to a00c2e0ecbaec366364cecb5efbdb456c8c543ef
removing really_exiting from globals.h, but the next commit fixes the
build failure.
