tchar.h, #defines, Cpp to D

[Lionello Lunesu]

The _X() and _T() macros need not be converted. D will automatically 
interpret a string constant as ascii (actually utf8!) or wide (utf16) 
depending on the variable. You should use alias for the XCHAR (and 
TCHAR) type:

// this should be in a translated tchar.h
version(UNICODE) {
alias wchar TCHAR;
alias strcpy _tcscpy;
//etc
} else {
alias ubyte TCHAR;//note that 'char' implies utf8
alias wcscpy _tcscpy;
//etc
}

alias TCHAR XCHAR;
alias _tcscpy STRCPY;
const XCHAR[] XRC = "\r\n";
//etc

I've only seen your TCHAR/XCHAR stuff, so can't comment on the rest.
