This works fine. Here is the output of `objdump -h' for the
stripped new-cygwin1.dll. The output for the unstripped one is
the same.

new-cygwin1.dll:     file format pei-i386

The reason why the stripped binary couldn't work on NT4 Sp5 and
W2K RC2 seems that `strip' over-stripped the .reloc section.
John R. Hanson pointed out this to me by a private e-mail yesterday.
I, however, didn't think the reason was so simple.

I'm very sorry. Thank for your effort.
