I see. What about adding a separate rule to Makefile.in just for
unixcalls.c and omit that file from C_SRC? That way you can control
again which parameters will be passed to gcc. As unixcalls.c is not a
"traditional" windows source file, but a bridge to the Unix system, I
think that approach should be OK.

According to MSDN, wsprintf() does not handle INT64 et all. So Wine is
correct when it does not either.
So dynamically linking to msvcrt seems to be the only possible solution.

You are right, it is NOT allowed in Wine code since it's not portable
between compilers. There WCHAR is the right choice. However it is for
Winelib applications (at least the docs suggest it). As Winefile is on
one hand a Winelib application but on the other part of the official
Wine distribution, I recommend to use WCHAR when you need Unicode
string literals - that's the safe side. ;-)

There are many Windows API functions that use a similar pattern. For
example the resource loading functions like LoadIcon() do the same, i.e.
they interpret the given resource name as WORD if HIWORD(pszResource) is
0 or as string otherwise. That's what MAKEINTRESOURCE() is all about. I
call it the C way of "function overloading". ;-)
