1) is it possible to use the toplevel Makefile with MSYS/MinGW to build 
the DLL ? Right now, only the static lib is built.

2) in win32/Makefile.gcc, the note line 23 says to change the dll name to 
zlib1.dll. But, line 27, the name is zlib1.dll

3) MSYS/MinGW : make -f win32/Makefile.gcc builds static, import and dll 
are built flawlessly

4) When i try to compile zlib with Visual Studio Express 2008, all the 
projects are ignored. I have to change, in the properties of the solution, 
the platform (switched from Itanium to win32). I also have to hack zconf.h 
so that unistd.h is not included. In zutil.h, off_t is used (line 166 for 
example). Maybe z_off_t should be used instead.

5) with ceGCC (for Windows CE), same problem with off_t. If i replace 
off_t by z_off_t, in zutil.h (lines 166 to 170), it compiles without 
error.

Note: If I pass to CFLAGS the following flags:

-Wmissing-declarations -Wmissing-prototypes -Wredundant-decls 
-Wwrite-strings -Wcast-align -Wall -W -Wextra -pedantic

I get these warnings on all platforms :

gzlib.c:203: warning: no previous prototype for 'gzopen64'
gzlib.c:274: warning: no previous prototype for 'gzseek64'
gzlib.c:362: warning: no previous prototype for 'gztell64'
gzlib.c:389: warning: no previous prototype for 'gzoffset64'

and:

a) on linux:

minigzip.c:54: warning: redundant redeclaration of 'unlink'
/usr/include/unistd.h:806: note: previous declaration of 'unlink' was here

b) with mingw32ce (didn't try with mingw):

minigzip.c: In function 'main':
minigzip.c:389: warning: implicit declaration of function 'setmode'
