Ooops.  Now it's a runtime failues with older snapshots.

Here's the deal:

zlib-1.1.3 minigzip.exe(linked to libz.dll) and minigzip-stat.exe(linked
statically), running 'make test':

       run env: 20000628     20000711
build env
20000628         OK             OK
20000711        FAIL            OK

The command that fails:

echo hello world | ./minigzip > foo

and gives a popup window that reads:

The instruction at "0x00401a98" referenced memory at "0x00000001". The
memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program

Is it expected that programs/dlls compiled with the new (20000711 and
later) libcygwin.a will fail with older installations?
