+	* stack.c (frame_command):  Always print.  Use new

+
 	* dwarfread.c:  Use <varargs.h>, since <stdarg.h> is not portable.

+	* xconfig/sun[34]os4:  Add note about strstr botch on sunos4.0.3c

+	* mipsread.c (fixup_undef_type):  New function.  If a struct /
+	union / enum is defined in a header file but nowhere else used,
+	(by typedefing, pointer referencing or declaration) the mipsread code
+	builds the complete tree for the structure but leaves its code as
+	TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
+	Guess its type based on the details of the members.
