Bugs

• Small memory leaks may occur when an exception is thrown and caught.
• My exception scheme is not properly linked in with the standard library exceptions. In particular, my scheme may fail to catch out-of-memory exceptions.
• Linux G++ 2.6.?: If you are using optimisation, the construct fabs(*X++) causes a problem. Write your own version of fabs (probably should call it something else) and don't inline it.
• If you are using my make files for Gnu or CC and you get a compile error then you must remove the .cxx file that was generated by (g)make before you can recompile.
