According to the latest sdk I have (2000), _tcsdup is supposed to map to
_strdup and _tcsicmp to _stricmp.

I think the catch is you are supposed to link with the msvcrt library
since these symbols are only exported there.

Now, pointing _tcsdup to strdup should not make any difference. However
I am not sure that _stricmp really behaves exactly like strcasecmp: you
would need to check how each of these handles accentuated characters and
locale.

Then the question is whether tchar.h should be considered to be a pure
msvcrt thing, i.e. don't use it if you don't link to msvcrt, or whether
we want to make is usable in Ansi mode with a regular C library.
Currently we set the macros based on _MBCS and _UNICODE. Maybe we need
to add a WINE_LIBC flag and add mappings to the native C library
routines?
