Bug ID: 57424
           Summary: msys2-64/cygwin64: mintty.exe not able to show
                    bash.exe output.
           Product: Wine
           Version: 9.21
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wineserver
          Assignee: wine-bugs@winehq.org
          Reporter: bernhardu@mailbox.org
      Distribution: ---
Cygwin in version 3.5.4 or later relies in having the WriteQuotaAvailable
member of a NtQueryInformationFile(FilePipeLocalInformation) query
to be non-zero.
This causes mintty.exe not being able to show the bash.exe output
when running in wine.
A bisect of cygwin1.dll led to this cygwin commit:
