>Description:
gcc gives an erronated "parse" error, when it's actually a semantic error when declaring a class that has a base class undefined.
The famous code:
//Start the file
class A 
	: public B
{
};
//End the file 
Class B is undefined here, and the error message says:
t.cpp:4: parse error before `{' token
I expect here an error that says : <<base class undefined>>!
