3 * For conditions of distribution and use, see copyright notice in zlib.h
12 * If you *really* need a unique prefix for all types and library functions,
13 * compile with -DZ_PREFIX. The "standard" zlib should be compiled without it.
14 * Even better than compiling with -DZ_PREFIX would be to use configure to set
15 * this permanently in zconf.h using "./configure --zprefix".
