the L"" constructs are not yet supported while porting code (which I assume you're doing)
This is a bit misleading, as it works in any reasonably recent gcc using the -fshort-wchar option (as you mentioned), or it will just wrok if you use winegcc (and if you have a reasonably recent version of gcc for the backend, of course :).
In fact, I would say winegcc is the recommended way for porting these days, and it will support L"" out of the box.
