While trying to build this package using rpmbuild I noticed several occurences
of lines like this:

gcc.archive

It looks like the native 'ar' is used (/usr/bin/ar) instead of
i686-pc-mingw32-ar. This might need some further investigation.


Another issue I noticed in the .spec file is this:
 if a2dll libboost_thread-mt.lib libboost_thread-mt "-lpthreadGC2"; then
As of mingw32-pthreads-2.8.0-8{.fc11,.fc12} it isn't necessary to use
'-lpthreadGC2' anymore. It should be sufficient to use just '-lpthread' here.


For the link errors in the testsuite libraries. I might have found out a way to
get it operational as shared libraries. Would it be possible to add a main()
function to those testsuite libraries which looks something like this:

int main(int argc, char **argv)
{
    void (*test_main_func) (int, char**);

    test_main_func = GetProcAddress(NULL, "test_main");
    if (!test_main_func) {
        printf("No test_main() function found\n");
        return -1;
    }

    test_main_func(arg1, arg2);

    return 0;
}
