| Well g++ 2.96 did a very good job at finding some issues in the code

Hmm, now I'm confused, I'm unsure about the original topic...
Anyway...

| one quick question if you don't mind:
| - is a class forward declaration sufficient for exception
|   or is the class interface needed also?
|   
| class except;
| class A
| {
|  public:
| void f() throw(except);
| };
| 
| or
| 
| <full class definition for except via #include for example>
| class A
| {
|  public:
| void f() throw(except);
| };
| 
| it seems that g++ 2.96 likes the second one and rejects the first one

Yes, the first construct is ill-formed since

15.4/1:
  [...] A type denoted in an exception-specification shall not be an
  incomplte type.  A type denoted in an exception-specification shall
  not denote a pointer or reference to an incomplte type, other than
  void*, const void*, volatile void*, or const volatile const*.
