Copy the files Makefile.w32, zlib.def, and zlib.rc from the msdos\
directory to the parent directory. Apply the following changes to
Makefile.w32 and then nmake -f Makefile.w32 zlib.dll. I will also
attach a text file of the diff just incase my mailer wraps the diff.

I fought with this recently and found that I needed to rebuild the
zlib.dll file. I used the instuctions in the README file of the
zlib-1.1.4.tar.gz file reading the instructions starting with "To
build a Windows DLL version, include..." I copied the Makefile.w32
into the base directory, changed the makefile to support
multi-threaded DLLs and then added the target for zlib.dll.
Unfortunately I don't have the changes on this machine, but I will see
if I can post them within a couple of days. After rebuilding the DLL
and copying it to the appropriate spot, it would read/write gzip
capture files.

I have made clean, run cleanbld.bat and remade everything.
Still ethereal won't open a .gz file.
The About box says it was built with zlib 1.1.4.

Thanks.
