[Bug 21320] New: wine/list.h has namespace conflicts with sys/queue.h

http://bugs.winehq.org/show_bug.cgi?id=21320

Summary: wine/list.h has namespace conflicts with sys/queue.h
           Product: Wine
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

sys/queue.h on FreeBSD, darwin, etc provide LIST_ENTRY macros which conflict
with those in wine/list.h ... this has led to problems such as:

http://trac.macports.org/ticket/22342

A workaround for this was pushed into wine a while back, but it is merely a
hackish workaround.  If you permute the order in which headers are included, or
if system headers happen to add an include on sys/queue.h, you may end up not
being able to build wine.  This is what happened in the above external ticket.

If you simply add a '#include <sys/queue.h>' to
/usr/include/dispatch/dispatch.h, wine stops building here on darwin.  I'm sure
it would be easy to find a similar case on FreeBSD.

One fix is to avoid conflicting with the sys/queue.h namespace and use
something like WINE_LIST_ENTRY
