newlib/winsup/mingw/include/io.h
Danny Smith 9fe2a2157b 2002-06-18 Casper S. Hornstrup <chorns@users.sourceforge.net> 
* include/_mingw.h (__MINGW_IMPORT): Check for prior definition before
	defining.
	* include/excpt.h (): Include windef.h not windows.h.
	* include/fcntl.h (_O_SHORT_LIVED): Add define.
	(_chmod): Add prototype.
        (_creat): Correct prototype.
	(SH_DENY*): Rename defines to _SH_DENY*.
	(SH_DENY*): Add Non-ANSI names for _SH_DENY*.
	include/stdio.h (_IOMYBUF, _IOEOF, _IOERR, _IOSTRG,
	_IOAPPEND): Add defines.
	(_wfindfirst): Correct prototype.
	(_wfdopen): Add prototype.
	* include/stdlib.h (_rotl, _rotr, _lrotl, _lrotr): Add
	prototypes.
	* include/string.h (_mbschr, _mbstok, _mbsncat): Remove
	 prototypes.
	(_wcsdup): Correct prototype.
	* include/mbstring.h: Remove comments about _mbschr, _mbstok,
	 _mbsncat being in string.h.
	* include/wchar.h (_wfindfirst): Correct prototype.
	* include/tchar.h (_tfdopen): Add _UNICODE mappings.
