+
+	PR ada/48835
+	* gcc-interface/Makefile.in: Add support for m68k-linux.
+	* system-linux-m68k.ads: New file based on system-linux-ppc.ads
+	and system-vxworks-m68k.ads.
+	* s-memory.adb (Gnat_Malloc): New wrapper around Alloc, returning
+	the memory address as a pointer not an integer.
+	Add Gnat_Malloc -> __gnat_malloc export.
+	* s-memory.ads: Remove Alloc -> __gnat_malloc export.
