1.6.9: 2008-03-10 Murray Cumming * glom/libglom/connectionpool.cc: discover_first_free_port() Reformat the code to make the use of ifdefs for various platforms clearer. Include errno.h and add a comment about how this is essential to make the code actually work. This stops Glom from starting a postgres instance on the same port that is used by an existing instance.
