Approximately 3 time faster is a significant improvement, but IMO,
anything more than a few seconds is still too "expensive."

What about an option to disable the sanity checking?  In this way,
Cygwin users do not need to learn new tricks, but powers user still get
the control they desire.

BTW, I tried to give cygcheck from the 2003-Sep-08 snapshot a ride.  The
ChangeLog and diff seem to indicate the required changes have been
completed.  Unfortunately, my timing showed no difference and objdump
showed no dependency on Mingw zlib:

    $ objdump -p cygcheck.exe | fgrep 'DLL Name:'
            DLL Name: msvcrt.dll
            DLL Name: msvcrt.dll
            DLL Name: ADVAPI32.DLL
            DLL Name: KERNEL32.dll

Is the above cockpit error on my part?

Thanks,
Jason
