Scary-looking but otherwise harmless changes allow me to build for Windows.

That is to say, with mingw32.  This amounts to the following:

 (1) break compat.c into compat_strlcpy.c and compat_strlcat.c
 (2) add compat_getsubopt.c (from OpenBSD) and test-getsubopt.c
 (3) add test-strptime.c for HAVE_STRPTIME
 (4) add ifdef bits here and there, where necessary
 (5) remove some harmless unportable stuff (u_char, localtime_r)

I've added the appropriate mdocml.zip target to the Makefile, too.
