Bug ID: 51796
           Summary: io.h and direct.h are missing from winelib
           Product: Wine
           Version: 6.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winelib
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

While I can use `unistd.h` and `dirent.h`, I have to rewrite code in order to
do that, and also have to have an abstraction layer, since these headers are
not available in Visual Studio.

It'd be nice if winelib had them.
