Steve Traylen updated AMQCPP-389:
---------------------------------

    Description: 
Building 

activemq-cpp-library-3.4.1-src.tar.gz

with

gcc-c++ 4.7.0

results in 

{noformat}
./decaf/util/AbstractQueue.h:63:13: error: 'offer' was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
./decaf/util/AbstractQueue.h:63:13: note: declarations in dependent base 'decaf::util::Queue<decaf::lang::Runnable*>' are not found by unqualified lookup
./decaf/util/AbstractQueue.h:63:13: note: use 'this->offer' instead
{noformat}

From: https://lists.fedoraproject.org/pipermail/devel/2011-December/160723.html

C++ lookup fixes, the C++ FE no longer performs an extra unqualified
lookup that it (incorrectly) performed in the past.  In some cases the
diagnostics includes hints how to fix the bugs, for PR24163 the
diagnostics looks like:
error: 'something' was not declared in this scope, and no 
declarations were found by argument-dependent lookup at 
the point of instantiation [-fpermissive] note: declarations in 
dependent base 'someclass<somearg>' are not found by unqualified lookup
note: use 'this->something' instead

http://gcc.gnu.org/PR24163

The trivial attached patch with solution recomended above corrects the 
problem.
