I suspect so.  I believe that some message is being issued when "Checking for shared library support...".  Patches are welcome.

Actually the comment says you should change the name *from* zlib1.dll.

I don't know why it says that, so if the comment needs to be changed, please let me know.

I will leave it to the studio meisters to figure that out.

Why?

Fixed.

Fixed.

Should be fixed.

In minigzip.c is this:

#if defined(MSDOS) || defined(OS2) || defined(WIN32) || defined(__CYGWIN__)
#  include <fcntl.h>
#  include <io.h>
#  define SET_BINARY_MODE(file) setmode(fileno(file), O_BINARY)
#else
#  define SET_BINARY_MODE(file)
#endif

So if setmode() isn't defined in fcntl.h (or io.h), then where is it defined?
