+Changes in 1.1.4 (11 March 2002)
+- ZFREE was repeated on same allocation on some error conditions.

+- Returned incorrect error (Z_MEM_ERROR) on some invalid data
+- Avoid accesses before window for invalid distances with inflate window
+  less than 32K.

+    Yes. zlib doesn't handle dates.
 
+ 2. Where can I get a Windows DLL version?

-  and contrib/visual-basic.txt
+    Make sure that before the call of compress, the length of the compressed

+    zero. For Visual Basic, check that this parameter is passed by reference
+    ("as any"), not by value ("as long").
 
-3) compress() returns Z_BUF_ERROR
+ 5. deflate() or inflate() returns Z_BUF_ERROR
 
-  Make sure that before the call of compress, the length of the
-  compressed buffer is equal to the total size of the compressed buffer
-  and not zero.  For Visual Basic, check that this parameter is passed
-  by reference ("as any"), not by value ("as long").
+    Before making the call, make sure that avail_in and avail_out are not
+    zero. When setting the parameter flush equal to Z_FINISH, also make sure
+    that avail_out is big enough to allow processing all pending input.
 
+ 6. Where's the zlib documentation (man pages, etc.)?
 
-4) deflate or inflate returns Z_BUF_ERROR
+    It's in zlib.h for the moment, and Francis S. Lin has converted it to a
+    web page zlib.html. Volunteers to transform this to Unix-style man pages,
+    please contact Jean-loup Gailly (jloup@gzip.org). Examples of zlib usage
+    are in the files example.c and minigzip.c.
 
-  Make sure that before the call avail_in and avail_out are not zero.
+ 7. Why don't you use GNU autoconf or libtool or ...?
 
+    Because we would like to keep zlib as a very small and simple
+    package. zlib is rather portable and doesn't need much configuration.
 
-5) Where is the zlib documentation (man pages, etc...)?
+ 8. I found a bug in zlib.
 
-  It's in zlib.h for the moment. Volunteers to transform this
-  to man pages, please contact jloup@gzip.org. Examples of zlib usage
-  are in the files example.c and minigzip.c.
+    Most of the time, such problems are due to an incorrect usage of
+    zlib. Please try to reproduce the problem with a small program and send
+    the corresponding source to us at zlib@gzip.org . Do not send
+    multi-megabyte data files without prior agreement.

+    check that you don't have old files libz.* in /usr/lib, /usr/local/lib or
+    /usr/X11R6/lib. Remove any old versions, then do "make install".
 
-7) There is a bug in zlib.
+10. I need a Delphi interface to zlib.
 
-  Most of the time, such problems are due to an incorrect usage
-  of zlib. Please try to reproduce the problem with a small
-  program and send us the corresponding source at zlib@quest.jpl.nasa.gov
-  Do not send multi-megabyte data files without prior agreement.
+    See the directories contrib/delphi and contrib/delphi2 in the zlib
+    distribution.
 
+11. Can zlib handle .zip archives?
 
-8) I get "undefined reference to gzputc"
+    See the directory contrib/minizip in the zlib distribution.
 
-  If "make test" produces something like
-     example.o(.text+0x174): 
-  check that you don't have old files libz.* in /usr/lib, /usr/local/lib
-  or /usr/X11R6/lib. Remove old versions then do "make install".
+12. Can zlib handle .Z files?
+
+    No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt
+    the code of uncompress on your own.
+
+13. How can I make a Unix shared library?
+
+    make clean
+    ./configure -s
+    make
+
+14. Why does "make test" fail on Mac OS X?
+
+    Mac OS X already includes zlib as a shared library, and so -lz links the
+    shared library instead of the one that the "make" compiled. For zlib
+    1.1.3, the two are incompatible due to different compile-time
+    options. Simply change the -lz in the Makefile to libz.a, and it will use
+    the compiled library instead of the shared one and the "make test" will
+    succeed.
+
+15. I have a question about OttoPDF
 
+    We are not the authors of OttoPDF. The real author is on the OttoPDF web
+    site Joel Hainley jhainley@myndkryme.com.
