Hi,

You should use proper dllimport attributes with your codes, but if you
are lazy, you can just add -Wl,--enable-auto-import when linking.

With the latter, you may run afoul if you have data dllimported, I'm not
too clear what else you may encounter.

With a recent binutils from cvs (2.20.51 series), you can safely ignore
this warning.
