Subject: [PATCH] 0029169: Configuration - fix compilation with undefined
 UNICODE on Windows

Eliminated usage of TEXT macros, usage of OSVERSIONINFO instead of OSVERSIONINFOW.
LoadIcon/LoadCursor are now used instead of LoadIconW/LoadCursorW
when passing macros to standard resources (which depend on UNICODE flag).
