All of the --with-*-includes and --with-*-libs switches accept a list
of directories, separated by spaces, e.g.

	./configure ... --with-libs='/usr/local/lib /usr/local/bin'

However, many DLLs have the DLL in .../bin with a matching import
library in .../lib; in that case, you only need to specify the .../lib
directory.

Note that you don't need to specify the default directories (/lib,
/bin, /include, which are aliased to /usr/lib etc) explicitly. The
compiler and linker will search those directories automatically.

Use --with-opengl=windows. What the --help output actually says is:

  --with-opengl           support OpenGL functionality (default: yes)

The default is "yes", which is an alias for "x11". Allowed values for
--with-opengl= are:

	n,no
	y,yes,x,x11,glx
	aqua,mac,osx,macosx,agl
	win,windows,mswin,wgl

For native windows OpenGL, use any of: win,windows,mswin,wgl.

--disable-x11 is bogus. It may be a typo for --disable-w11, but that's
the default. --enable-w11 provides a version of XDRIVER which uses the
native Win32 API (GDI etc) instead of X, but display drivers only work
under Cygwin (they require Unix-style sockets; WinSock doesn't work).
