I don't understand why this change is needed. At that point, windows.h
should already
have been included using the following sequence:

file-ops.h > str-vec.h > Array.h > lo-utils.h > windows.h (around line 69).

I think that the problem you have is a symptom of another problem:
HAVE_LOADLIBRARY_API
is not defined, that means that the configure check for LoadLibrary failed.

The patch above is not a problem for MSVC. But when something does not work
under MinGW, the first thing you should ask yourself is "Damn, why does it work
under MSVC?". Because if it wouldn't work, then I would also have the problem,
and I would probably fix it ASAP... :-)
