Now all you should have to do is make sure the ctors and dtors section are
in your linkcmds.  The file rtems-ctor.cc should only be needed on non-GNU
toolsets or the unix port.  The constructors are supposed to be invoked
via the shared main or the ELF magic now.

Built with egcs all the time along with the STL. :)

The places to look at for examples are librtems++, the cdtest, and the
test for librtems++.

I do believe there is still a problem with how many times global
constructors/destructors are invoked.
