No, you misunderstood.

The Xt library has not yet been compiled under Cygwin 1.5.x.  Until it is,
it is unsafe for use by apps compiled under 1.5.x.  This is a side effect
of the 64 bit implementation method choice.

Since the call to stat is redirected to stat64 at link time, pre 1.5.x
static libs (like Xt) get the redirection, but did not allocate a stat64_t
type.  Dll's are "pre linked", and so do not suffer this problem.

Does that help, or is it still to vauge?
