* win/tclWinFile.c: corrected the symbolic link handling code to

	allow it to compile.  Added real definition of REPARSE_DATA_BUFFER
	(found in winnt.h).  Most of the added definitions appear to have
	correct, cross-Win-version equivalents in winnt.h and should be
	removed, but just making things "work" for now.
