Mps: attempt to fix w3i3mv "all" build with vc7:

(unknown if these changes are effective, but they should be safe)
1. mpm.c: +1 to array size to make room for terminator of string initializer;
2. testlib.c: disable warning 4702: unreachable code, for va_end.
(integrate from version/1.106/...@158055)
