Argh. Let me write "git commit -a" on the inside of my brown paper bag,
so that I actually send out the fix sitting in my working tree, not the
half-finished thing I ran "git add" on.

Subject: [PATCH] compat/mingw: brown paper bag fix for 50a6c8e

Commit 50a6c8e (use st_add and st_mult for allocation size
computation, 2016-02-22) fixed up many xmalloc call-sites
including ones in compat/mingw.c.

But I screwed up one of them, which was half-converted to
ALLOC_ARRAY, using a very early prototype of the function.
And I never caught it because I don't build on Windows.
