b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
3. At presenet (2012/11/02), this example builds only with exceptions
disabled (CONFIG_UCLIBCXX_EXCEPTIONS=n). And even then, it will
not run.
The reason that the example will will not run on the simulator has
to do with when static constructors are enabled: In the simulator
it will attempt to execute the static constructros before main()
starts. BUT... NuttX is not initialized and this results in a crash.
To really use this example, I will have to think of some way to
postpone running C++ static initializers until NuttX has been
initialied.
