Hi everybody,

I am a newbie in libwww and while I tried to use it I've got the
following problems:

0. I use WinNT 4.0 with Microsoft Visual C++ V5.0 and w3c-libwww-5.1i
(but it's not a problem :-) )

1. While I trying to build library with _CONSOLE wwwzip.dll bulding
fails with the following:
--------------------Configuration: wwwzip - Win32
Debug--------------------
Linking...
HTZip.obj : error LNK2001: unresolved external symbol _inflateEnd
HTZip.obj : error LNK2001: unresolved external symbol _inflate
HTZip.obj : error LNK2001: unresolved external symbol _inflateInit_
..\..\..\Bin\Debug\wwwzip.dll : fatal error LNK1120: 3 unresolved
externals
Error executing link.exe.

wwwzip.dll - 4 error(s), 0 warning(s)

I suggest the following change in zconf.h:

/* Compile with -DZLIB_DLL for Windows DLL support */
#if (defined(_WINDOWS) || defined(WINDOWS) || defined(_CONSOLE)) &&
defined(ZLIB_DLL)

istead of

/* Compile with -DZLIB_DLL for Windows DLL support */
#if (defined(_WINDOWS) || defined(WINDOWS)) && defined(ZLIB_DLL)

2. All my attempts to use comline.exe to get documents from *very* busy
sites (like www.cnn.com or www.microsoft.com) were failed with the
following (using the following command: comline -single -vuph
http://www.cnn.com )

<<< ans so on >>>

Usnig webbot I've got the same messages...

But I can not find solution to this by myself (using -timeout 100 does
not solve the problem). 

3. Let me suggest to make possibility to log all verbose messages into
some log file? It will make sence...

Any help will be really appreciated.

Kind regards,

Vladimir Kozlov.
