That's a Win9x oddity.

Fortunately, I have VMware with a Win98 image here.

The problem is that bloda.c calls NtQuerySystemInformation without using
any kind of autoload.cc-type indirection, and so cygcheck gets a hard
dependency on ntdll.dll which doesn't exist on 9x/ME.  We need to do one
of:

- Revert the bloda-check feature on the 1.5 branch
- Check windows version at runtime and only do NT calls through
LoadLibrary/GetProcAddress
- Use the autoload.cc trick in cygcheck

If we're going to make releases from the 1.5 branch then I don't think
it's quite acceptible just yet to shaft 9x users, after all that's the
whole point of the branch.
