RE: [Dev-C++] Make switch condition an enum

[Per W. <pw...@ia...>]

The _T(x) is a macro used by a Microsoft Developer Studio, the wxWindows
framework etc, to handle wide/non-wide, characters. All you have to do is
to #define _UNICODE (or sometimes #define UNICODE, or in wxWindows
#define wxUSE_UNICODE 1) to switch all "tagged"
strings to wide character strings.
