Preserve the last error when restoring the error mode.

[Peter Rosin]

Hi!

As promised in the other thread, here's a patch (on top of the
thread-error-mode-2.patch) to ensure that the reported error is
the error from the LoadLibrary call.

Cheers,
Peter

        Preserve the last error when restoring the error mode.
        * libltdl/loaders/loadlibrary.c (wm_open): Don't rely on
        SetThreadErrorMode (or SetErrorMode) to not clobber the last
        error.
