Does C++ std::queue really conflict with C header 'struct queue'?

[neroden at twcny dot rr dot com (Nathanael Nerode)]

The following hunk of code from fixinc.svr4 purports to fix a problem, which I
think may not be a problem.

The claim is that 'struct queue' in sys/stream.h conflicts with the
'queue' class in C++ headers.  This seems wrong to me because the C++
queue class is in namespace std, and I don't see why the sys/stream.h
version would be.

Am I missing something?  If the fix is still needed I will add this fix into 
standard fixincludes; if not I will delete it entirely.
