MinGW build

[Curt Arnold]

I'm still unable to get past unresolved references when linking  
shared libraries using MinGW.  The same problem appears occurs with  
either MinGW with a 4.1.1 gcc or a stock gcc.  I've attached a  
description and instructions to reproduce the problem as part of the  
MinGW build bug (https://issues.apache.org/jira/browse/LOGCXX-74).  I  
would appreciate anyone else interested in a MinGW build  
(particularly Bob Rossi) could check that you see the same problems  
on your installation and offer any fixes.  If can't come up with one  
here, will see if the MinGW mailing list might be able to spot the  
problem.
