Hi,

I'm having some problems with gcc 3.2 and __attribute__((deprecated))=20
when used in combination with inline functions. I need to add the=20
attribute to quite a few methods in several classes. These deprecated=20
methods are implemented inline, as in this example:

  class X {
  public:
    X() {}
    void foo() {}
  };

But this doesn't compile ("parse error before `{' token"):

  class X {
  public:
    X() __attribute__((deprecated)) {}
    void foo() __attribute__((deprecated)) {}
  };

I found that this works:

  class X {
  public:
    __attribute__((deprecated)) void foo() {}
  };

but I didn't find such use of __attribute__ in gcc documentation, so=20
I'm not sure it will continue to work in future gcc versions. More=20
importantly, it doesn't work with constructors, this doesn't compile:

  class X {
  public:
     __attribute__((deprecated)) X() {}
  };

The only working solution I found so far is to move the implementation=20
outside of class { ... } statement:

  class X {
  public:
    X() __attribute__((deprecated));
    void foo() __attribute__((deprecated));
  };

  inline X::X() {}
  inline void X::foo() {}

But I'd like to avoid it if possible both because of the amount of=20
deprecated methods and because inline implementation at the line=20
pointed to by gcc warning serves as a hint how to fix code that uses=20
deprecated calls.

Is there some way to do what I'm trying to?

Thanks!
Vaclav Slavik
