- * This header file is used to hijack the include of "zlib.h" from libpng on
- * Macos. We do that to be able to build on macos 10.13 or later, but still
- * keep binary compatibility with older versions (as specified to configure).
- *
- * The problem is that in 10.13, Macos shipped with a newer version of zlib,
- * which exports the function inflateValidate. There is a call to this
- * function in pngrutil.c, guarded by a preprocessor check of ZLIB_VERNUM being
- * high enough. If we compile this call in and link to the newer version of
- * zlib, we will get link errors if the code is executed on an older Mac with
- * an older version of zlib.
- *
- * The zlib.h header in Macos has been annotated with Macos specific macros that
- * guard these kinds of version specific APIs, but libpng is not using those
- * checks in its conditionals, just ZLIB_VERNUM. To fix this, we check for the
- * MAC_OS_X_VERSION_MIN_REQUIRED macro here and adjust the ZLIB_VERNUM to the
- # known version bundled with that release. This solution is certainly a hack,
- * but it seems the affected versions of zlib.h are compatible enough for this
- * to work.
