Now, this doesn't generate warnings:
class A; class B*;
int foo(A*, B*);
struct A {
friend int foo(A*, B*);
};
but this generates
struct B {
friend double foo(A*, B*);
};
which is correct, since they have different return types.
See the redefined.i file for most cases where
repeated (but not redefined) declarations are
not generating warnings now, such as:
// no warning
#define REPEATED 1
#define REPEATED 1
// yes warning
#define REDEFINED 1
#define REDEFINED 2
this is following the C, C++ and preprocessor
standard behavior.
The function 'need_redefined_warn(..)' was added to
util.c, if some strange corner appears, and therefore,
the parser.y file doesn't need to be changed latter.
Also, the redefined warning format in parser.y
was changed, so now it respond to William's -Fmicrosoft
flag.
