+Subject: [PATCH] jpeg_memsrcdest: extend feature check
+
+libjpeg.h in OpenEmbedded master (from libjpeg-turbo 1.5.0) provides
+these methods if "JPEG_LIB_VERSION >= 80 ||
+defined(MEM_SRCDST_SUPPORTED)".
+
+The support for the jpeg_mem functions was added even when not
+emulating the libjpeg8 API, controlled via the MEM_SRCDST_SUPPORTED
+define, so checking for the version alone is not enough anymore.
+
+See https://github.com/libjpeg-turbo/libjpeg-turbo/commit/ab70623eb29e09e67222be5b9e1ea320fe5aa0e9
+
+This fixes errors about conflicting declarations (signed vs. unsigned
+char).
