--target= in my docs was just a slipup... --host= is right.

It would actually only take a single added default
(glib_cv_stack_grows=no) to cross-compile to mingw32 withouat
any cache file at all. So, I might do that.

I don't want to be responsible for maintaining cache files;
there is a pretty much infinite possible set, and there is
no way I could keep submitted files up to date.

Probably the build/ directory needs some help for cross-compilation;
probably simply adding:

 AC_CHECK_TOOL(WINRES, winres)

to configure.in, and then using $(WINRES) instead of winres
in the Makefile.am.

Note the mention of "partially working" in my mail....
I've never successfully gotten a win32 build past GLib either 
cross or natively, honestly. 

Supposedly J. Ali Harlowe was having some success getting everything 
cross-compiled from Linux to Windows; I haven't seen full details
of what he was doing, however.
