+	target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
+	Remove to_call_function and target_call_function, since it
+	always calls the same thing (call_function_by_hand).
+	* core.c, exec.c, solib.c:  Rename target_ops sections =>
+	to_sections, etc.
+	* infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,

+	messages when the current language changes.  FIXME.
+	* xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
+	complaints about volatile functions.
+	* xm-sysv4.h (HAVE_MMAP):  Define.

+Thu Feb 20 09:04:18 1992  Fred Fish  (fnf at cygnus.com)
 
 	* defs.h:  Include ansidecl.h and PARAMS macro.  Use PARAMS
 	to make prototypes for all functions declared here.
