+
+ Lay foundations for new printf() function family implementation.
+
+ * ofmt_stub.s: New file; implement forward compatibility stub for...
+ (_get_output_format): ...this MSVCR80.DLL and later function.
+
+ * Makefile.in (SRCDIST_FILES): Add ofmt_stub.s.
+ (NM, OBJCOPY): New macros; define them with AC_SUBSTed values.
+ (sym_prefix, NM_LOOKUP, MINGW_REPL_FUNCS): New macros; define them.
+ (lib%.a): Include ofmt_stub.o when import library does not already
+ advertise availability of the _get_output_format() function;
+ Add alias stubs for MINGW_REPL_FUNCS, such that...
+ (__msvcrt_printf): ...is an alias for Microsoft's printf().
+ (__msvcrt_fprintf): ...is an alias for Microsoft's fprintf().
+ (__msvcrt_sprintf): ...is an alias for Microsoft's sprintf().
+ (__msvcrt_vprintf): ...is an alias for Microsoft's vprintf().
+ (__msvcrt_vfprintf): ...is an alias for Microsoft's vfprintf().
+ (__msvcrt_vsprintf): ...is an alias for Microsoft's vsprintf().
+ (clean): Add msvcr*.def.
+
+ * configure.in (NM, OBJCOPY): Use AC_CHECK_TOOL to specify them.
+ * configure: Regenerated.

+ * A trivial stub, to replace the _get_output_format() function.

+ * _pformat() requires this function, which is provided by MSVCRT runtimes

+ * versions of MSVCRT, (those which do not already advertise availability of
+ * any exported _get_output_format() function); this will permit _pformat()
+ * to transparently interoperate with all supported versions of MSVCRT.
+ * (Likewise for CRTDLL).
