AW: winefile: UNICODE

I assume you only need include/msvcrt for unixcalls.c to be able to
include tchar.h. I assume the reason why tchar.h only works with msvcrt
is that gcc uses 4 bytes for wchar_t and wcs*() functions. Although you
can force gcc to use only 2 bytes (like it is the case in Windows), the
glibc wcs*() will most likely not behave correctly.

So I see two solutions:
(1) make a hard break and change the whole winefile to Unicode. For
unixcalls.c you can rely on the Windows API for manipulating Unicode
strings. Before calling the Unix functions, convert the Unicode string
to Ansi using WideCharToMultiByte(). Don't forget to add "-fshort-wchar"
to gcc options to get a 2 byte wchar_t.

(2) use TCHAR type. For unixcalls.c just be sure to include winnt.h
(should be included automatically). It defines the TCHAR type and the
TEXT() macro. For string manipulation you can again rely on the Windows
API functions like lstrcpyn, lstrcat etc.

Either way you can avoid to use msvcrt for unixcalls.c.
