2008-07-28 Keith Marshall <keithmarshall@users.sourceforge.net>
|
||||
|
||||
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.
|
||||

||||

|
||||
* include/ctype.h (_imp____mb_cur_max): Correct spelling.
|
||||
* include/ctype.h (_imp____mb_cur_max): Correct spelling.
|
||||
(_imp____mb_cur_max_dll): Likewise.
|
||||
|
||||
2008-07-04 Danny Smith <dannysmith@users,sourceforge.net>
|
||||
|
||||
* include/stdio.h (swprintf, vswprintf): Guard with #ifndef __STRICT_ANSI__
|
||||
* include/wchar.h (swprintf, vswprintf): Likewise.
|

* include/stdio.h (swprintf, vswprintf): Guard with #ifndef __STRICT_ANSI__

|

*
|

* _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).
