How to get _T( ) macro definition for UNICODE?

[Nagasai sowmya]

I have Unicode application which uses _T( ) macro as

[code]
#ifdef UNICODE
#define _T(x) L ##x
#else
#define _T(x) x
[/icode]

GCC compiler maps L to wchar_t which is 4 bytes on UNIX platforms. Now I need to have L defined in such a way that it takes 2 bytes. For this I used -fshort-wchar gcc flag, but this option is not available on some flavour of AIX machine on which I need to port my application.

Please can anyone suggest a way to define _T(x) or any other way such that in UNICODE, _T(x) gets always defined to 2byte wide character string even without using -fshort-wchar gcc option?

Look at the _T macro that Microsoft uses with TCHAR to switch between ASCII/UNICODE.
