[Bug 16749] New: kernel32/tests: wrong char type

http://bugs.winehq.org/show_bug.cgi?id=16749

           Summary: kernel32/tests: wrong char type
           Product: Wine
           Version: 1.1.12
          Platform: Macintosh
        OS/Version: Linux
            Status: NEW
          Keywords: source
          Severity: minor
          Priority: P2
         Component: build-env
        AssignedTo: wine-bugs(a)winehq.org

codepage.c:228: warning: comparison is always false due to limited range of
data type
codepage.c:244: warning: comparison is always false due to limited range of
data type

changing mbc to be a signed char rather than char seems the obvious solution,
but that breaks things further:
codepage.c:226: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
codepage.c:233: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
codepage.c:242: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
codepage.c:251: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
codepage.c:262: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
codepage.c:328: warning: pointer targets in passing argument 5 of
‘WideCharToMultiByte’ differ in signedness
