newlib/winsup/mingw/include/stdio.h
Earnie Boyd 6126c12345 * include/direct.h: add guard around MSVCRT-only prototytpes 
* include/io.h: add __int64 struct definitions and function prototypes;
		 add guard for MSVCRT-only prototypes
	* include/limits.h: add ISO C9x macros LLONG_MIN, LLONG_MAX, ULLONG_MAX
	* include/stdio.h: add wchar function prototypes (__MSVCRT__);
		 put wchar functions together to make sync with wchar.h easier
	* include/stdlib.h: add wide char functions (__MSVCRT__)
	* include/string.h: add string collation functions ( __MSVCRT__)
	* include/sys/stat.h: add __int64 struct and function ( __MSVCRT__)
	* include/tchar.h: add macros and macro function definitions
	* include/wchar.h: add wide char function prototypes ( __MSVCRT__ );
		enclose more functions in __MSVCRT__ guard;
		some oldname wide char function prototypes #if (0)'d
	* profile/gmon.h: add guard around BSD-ish typedefs
