	# rpng's IDAT inflate needs zlib. Always build the bundled subset

	# wiiu). The gz*/compress translation units are simply not compiled;
	# their zlib.h declarations are harmless. Z_SOLO is deliberately NOT
	# used: it removes the default zcalloc/zcfree allocators and makes
	# inflateInit/deflateInit reject the Z_NULL allocators that
	# libretro-common's trans_stream_zlib passes.
	# Z_PREFIX renames every public symbol to z_* so a statically linked
	# core can never collide with the frontend's own zlib. The one
	# exception is z_errmsg: it already starts with z_, so zlib 1.2.8's
	# Z_PREFIX list omits it even though every zlib in the world exports
	# that exact name -- rename it explicitly.
