Recover from errors

Recover from errors

[Grigorio V. Moshkin]

Hi!

First, thanks to Andrew Pinski <pinskia@physics.uc.edu>, for his fast and 
exact replay to my previous question!

I am porting one large windows application to linux. Code is formerly platform 
independent. But, Microsoft Visual C++ (MSVC) 6 is very unserious with ISO 
C++ standard. For exemple, consider the fragment:

class A {
public:
	virtual void func() throw (C, D);
};

class B: public A {
public:
	void func();
};

Of course, gcc notices the error:
"looser throw specifier for `virtual void func()'". And, it's ISO C++ strict 
rule. But MSVC doesn't emit an error and simply compiles that code.

The problem is there are too many fragments of code above with this tipical 
error and other few tipical errors.

Does gcc allow (maybe via an undocumented option or slight SOURCE HACKING 
(thats because I write to gcc-BUGS mailing list)) to generate C++ code with 
this tipical errors FIXED? I ask just because I see, gcc does collect all 
SUFFICIENT (enough) INFO to FIX that tipical erros.

MSVC6 predates the ISO C++ standard.

GCC is not able to reproduce the C++ source code it compiles on the output, let
alone modified. Just fix the bugs in your code like everyone else does :)
