The current plan is to keep MariaDB working on Windows.

This looks to be due to a missing ssize_t definition.

the ANSI C standard. You should probably add a windows definition, maybe

    typedef ptrdiff_t ssize_t

Are these warnings also in MySQL source? I would think so, don't look fatal
from a quick glance.

I guess Windows doesn't have ftruncate. Maybe there is a mysys portable
replacement that you can use, or maybe you can wrap that part of the unit test
in #ifdef HAVE_FTRUNCATE.
