+/* When a specific build of zlib is done on Windows, it is either a

+ * distributed. The zconf.h thus knows a priori whether the
+ * corresponding library was built as a DLL or not. Requiring the
+ * library user to define ZLIB_DLL when compiling, and intending to
+ * link against the import library for such a DLL build, is
+ * silly. Instead just unconditionally define ZLIB_DLL here as this
+ * build is a DLL, period.
+ * Similarly, when a specific build of zlib is done on (32-bit)
+ * Windows, it either uses the WINAPI calling convention or not. A
+ * user of a prebuilt library can not choose later. So it is pointless
+ * to require the user to define ZLIB_WINAPI when compiling. Instead,
+ * just have a specific copy of this zconf.h that corresponds to that
+ * build of zlib. In the case here, we don't build zlib with WINAPI,
+ * so ignore any attempt by a misguided user to use it.
