luatex panics after update of zlib to 1.3.1

[Heiko Oberdiek]

Hallo,

after the latest update of Cygwin, especially
zlib from 1.3 to 1.3.1, luatex and related
programs (lualatex, texdoc, ...) abort
with a panic error: the version 1.3 of the header files
of zlib (compile time) does not match the version 1.3.1
of the dynamic library (runtime).

I assume, luatex from texlive-collection-luatex
needs to be recompiled with the updated zlib
sources.

Best regards
   Heiko
