Exceptions

MICO's exceptions handling capabilities suffer a lot from the limited exceptions handling support in the GNU C++ compiler, namely:

• exception handling is only supported on very few platforms, notably on Sun SPARC, Intel x86, Motorola 68k, and IBM RS/6000.
• throwing class X and catching a base class of X does only work if you turn on Runtime Type Information (RTTI) support by using the -frtti option. But if you compile one file using -frtti you have to compile all files using this option, including the iostream- and all other C++ libraries. Besides this g++'s RTTI support ist still very buggy.
• you cannot throw exceptions from a shared library into user code (trying this gives you a segmentation fault).
• there seems to be a memory leak in the compiler generated exception handling code.

These limitations are the reason for the somewhat strange exception handling design in the current version of MICO.
