I've tested the attached version (identical, except for the
<sys/errno.h> bits) by building both i686-pc-linux-gnu x powerpc-eabi
and i686-mingw32 x powerpc-eabi debuggers.  (The latter was built on an
x86-64 GNU/Linux box using an i686-pc-linux-gnu x i686-mingw32 cross
compiler.)

	* configure.ac (USE_WIN32API): Define it.
	* configure.in: Regenerate.
	* config.in: Likewise.
	* emul_netbsd.c (write_timezone): Guard with HAVE_GETTIMEOFDAY.
	* emul_unix.c (do_unix_mkdir): Handle Win32 1-argument mkdir.
