Bug ID: 52606
           Summary: build on Cygwin fails: error: ‘CP_UTF8’ undeclared (in
                    libs/xml2)
           Product: Wine
           Version: 7.3
          Hardware: x86-64
                OS: Windows
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P2
         Component: msxml3
          Assignee: [e-mail]
          Reporter: [e-mail]

(This is continuation from the bug 52374)

After faking l3codeca.acm, make then fails in libs/xml2.

MB_ERR_INVALID_CHARS is undeclared here too.  Also declaration of
MultiByteToWideChar() is implicit:

If I fake this object file, it leads to dlls/msxml3/msxml3.dll build failure.
