Bug ID: 39241
           Summary: msvcrt:string fails in a mixed locale configuration
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: msvcrt
          Assignee: [e-mail]
          Reporter: [e-mail]

The following error only happens on the mixed locale WineTest box.

string.c:2654: Test failed: ret = d0

That box (fg-win7u64-1spie9-mx) has the following locale settings:
  Formats=Inuktitut (Syllabics, Canada)
  Location=Israel
  Language=German (Germany)
  SystemLocale=Japanese (Japan)

So either it's comparing the result of two functions that use different
locales, or, since it's the tolower test, it depends on uppercase / lowercase
relationships that don't hold in all locales.

This tests regression was introduced by the following commit:

msvcrt: Improve tolower tests.
