Is this a required behaviour?  Section 5.5.2 of the 98 report seems to 
say so, but it's not exactly given in ironclad terms.  In other words, 
is it required for the compiler to provide enough information when 
compiling a module that when importing the module later, it can see that 
a name is being re-exported?

If so, then we're in happy shape; the move of some definitions from 
Network.BSD to Network.Socket shouldn't be a problem.

Thanks,
