Irina Boverman commented on QPID-4599:
--------------------------------------
The gcc 4.1 -fvisibility option is said to
...very substantially improve linking and load times of shared object
libraries, produce more optimized code, provide near-perfect API export and
prevent symbol clashes. It is strongly recommended that you use this in any
shared objects you distribute.
