	* win/tclWinFile.c: [Bug 3388350] mingw64 compiler warnings

2012-03-11  Donal K. Fellows  <[email protected]>

	* doc/*.n, doc/*.3: A number of small spelling and wording fixes.

 *
 * Note on converting between Tcl_WideInt and strings. This implementation (in
 * tclObj.c) depends on the function
 * sprintf(...,"%" TCL_LL_MODIFIER "d",...).
