+
+	* gcc/gcc.c (main): Add support for external spec file via the GCC_SPECS env var
+	and move the process of the user specifed specs.
+
+    This allows us to easily control pie/ssp defaults with gcc-config profiles.
+    Original patch by Rob Holland
+    Extended to support multiple entries separated by ':' by Kevin F. Quinn
+    Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
+    Modified to process the GCC_SPECS env var befor DRIVER_SELF_SPECS by Magnus Granberg
