>Description:
Gcc 3.0.2 (i686-pc-linux-gnu) has a quirk in which it does not
catch ambiguous method definitions.  If compiling class simple
(with -c), 3.0.2 will fail in the assembly stage, citing
"Error: Symbol xyzfuncEv already defined."  Inlining avoids
the quirk.

Gcc 2.96-MDK8.1 does the right thing by informing the user.


class simple
{
  public:
    void func();
    int func();
};

void simple::func() { }

int simple::func() { return 0; }
