Good to know that 64-bit MinGW is working - that said, I thought the MinGW port
was broken in 3.12.1 or is that not affected with the 64-bit compiler? Could
you share details on how you configured OCaml?

I use the following two commands to compile zlib 1.2.5 (with shared lib
support) with normal 32-bit mingw:
sed -i -e "s/MODE=0/MODE=1/" -e "s/)gcc/\0 -mno-cygwin/" win32/Makefile.gcc
make BINARY_PATH=C:/Dev/OCaml/bin LIBRARY_PATH=C:/Dev/OCaml/lib
INCLUDE_PATH=C:/Dev/OCaml/lib -f win32/Makefile.gcc all install
Presumably a few tweaks at the top of Makefile.gcc should allow you to compile
a 64-bit version?
For camlzip 1.04 I add the following META file (borrowed from BSD ports, IIRC):
---
name="zip"
version="1.04"
description="reading and writing ZIP, JAR and GZIP files"
requires="unix"
archive(byte)="zip.cma"
archive(native)="zip.cmxa"
linkopts = ""
---
You need to edit its Makefile - change ZLIB_LIB to -lzdll if you want to link
against zlib1.dll (-lz will give you static linking). You need to change
ZLIB_LIBDIR to be where you installed your custom zlib or the resulting binary
will be linked against Cygwin's zlib (for me that's C:/Dev/OCaml/lib,
therefore). I then build with make all allopt and install with ocamlfind
install camlzip *.dll *.a zip.{cmxa,cm[aix],mli} {zlib,gzip}.{cm[ix],mli} META
The examples work and definitely don't depend on cygz.dll
HTH,
David
