   Profiling is not supported. Constructors and destructors are not working
(yet). There is only a crude simulator setup for 32-bit Linux/x86.
Code+data+stack is limited to 64 kB, but can relatively easily be increased
to 64 kB code + 64 kB data+stack.

   That is another 16-bit x86 attempt. There is mention of a third one on
the list: <URL:http://gcc.gnu.org/ml/gcc/2005-12/msg00642.html>.
