Fwd: [ns] AIX compilation

[Aaron Harwood]

Well, I finally managed to compile ns on the IBM machine (specs below), 
but using g++ rather
than vacpp:

[aharwood at mungera] ns-2.26 [1:77] g++ --version
2.9-aix51-020209
[aharwood at mungera] ns-2.26 [1:78]

However one problem is now that ns tends to freeze (completely freezing
the terminal) when terminating. It passes all but the following tests:

validate overall report: some tests failed:
      ./test-all-plm ./test-all-wireless-tdma ./test-all-diffusion3

One of the tests failed because I killed the test process after it took 
more than 10 minutes.

Some things I needed to do in order to get a compilation of ns:

-I/usr/include so that snprintf(...) was explicitly declared

avoid inclusion of some headers by using additional tests with 
defined(_AIX)

changed virtual declarations as the following example:

virtual void recv(Packet*, Handler* callback = 0) = 0;

to

virtual void recv(Packet*, Handler* callback = 0) {};

It is this last change that I suspect may be causing a freeze.

Any suggestions?
