Well, sort of, if you are expecting cygcheck to be linked with a mingw
zlib DLL. zlib is linked statically.
I don't know why you aren't seeing a speedup. It's substantial on my
system. On my PII 500 at work, the difference is 55 seconds for the new
cygcheck and 1:29 on the old. That's not as good as my previously
posted figures but it should still be noticeable. In fact, if you are
running from a console window you can even see the difference in that
the title bar doesn't flicker.
