Here's part 1 of those details.

First, running the test suite resulted in some failures.
test-system-cmds failed because it uses '..' quoting on the command
line, which the Windows shell doesn't support.  Fixed thusly:

Next, test-unwind failed because it assumed that either $TMPDIR or
'/tmp' will exist, none of which can be counted upon on Windows.
Here's the fix for that (the declaration of mkstemp avoids compiler
warning):

Finally, the tests in check-guile fail because they unconditionally
use features that are not compiled into the MinGW build or not
supported by it, like 'lstat', AF_UNIX in sockets, etc.  Moreover,
whenever a test fails, the run stops without running the rest of the
test.  Is there a way to skip tests that are known to fail?  I see
that renaming the corresponding test files to not have the .test
extension would probably do the trick, but is there a better way?  For
that matter, is there a way of forcing the test run to continue even
if some test failed?  (I would actually suggest to skip tests
automatically based on unsupported features.)

Thanks.
