Not for me.  The reason for this patch was that all files were displayed
as sockets on BeOS, which doesn't have sockets.

I think we should keep that code more symmetric than it used to be.  I 
think I'll take this approach:

#ifndef S_IFDOOR 
#   define S_IFDOOR 0 
#   define S_ISDOOR(x) 0 
#endif 

and the same for all other S_IF - S_IS pairs.  That's what it should be if 
S_IFDOOR is not defined, and if it's defined, then it's reasonable to 
expect S_ISDOOR to be defined as well.
