	* configure.in: Add a check for `struct utimbuf'; needed by MonoPosixHelper.
	* support/map.c, support/map.h: Refresh -- to add Utimbuf copy conversion functions.
	  - Includes latest-and-greatest create-native-map output.
	  - Mono's Reflection output has changed as well --
	    FieldInfo.GetValue().ToString("x") is now "correct" for the underlying
	    type, so `short' enums are 0x0000, etc.
	  - Member sorting is now case-insensitive.
