Hi cygwin people,

I have found a problem with the _T macro definition as it is defined in
w32api/include/winnt.h: "#define _T TEXT" does not compile correctly the
following small program:

------  Cut Here  ------  Cut Here  ------  Cut Here  ------  Cut Here  ------
 #include <windows.h>
 #define __DIR "dir"

 main() {
        size_t len = wcslen(_T(__DIR)) + wcslen(_T("dir"));
        exit(len);
 }
------  Cut Here  ------  Cut Here  ------  Cut Here  ------  Cut Here  ------

In addition, the Microsoft VisualC programming manual also says that _T macro
is identical to _TEXT macro, which is not defined in winnt.h (but TEXT is
defined).

You will find an obvious patch for these 2 problems appended to this mail:
1) _T object-like macro is replaced by _T(q) function-like macro
2) TEXT macro definition is replaced by _TEXT
3) If TEXT macro is not defined, then define TEXT function-like macro as
	being identical to _TEXT one

Best regards,
-Eric
