Version 2.0.10 (in progress)
============================
2013-02-18: wsfulton
Deprecate typedef names used as constructor and destructor names in %extend. The real
class/struct name should be used.
typedef struct tagEStruct {
int ivar;
} EStruct;
%extend tagEStruct {
EStruct() // illegal name, should be tagEStruct()
{
EStruct *s = new EStruct();
s->ivar = ivar0;
return s;
}
~EStruct() // illegal name, should be ~tagEStruct()
{
delete $self;
}
}
For now these trigger a warning:
extend_constructor_destructor.i:107: Warning 522: Use of an illegal constructor name 'EStruct' in
%extend is deprecated, the constructor name should be 'tagEStruct'.
extend_constructor_destructor.i:111: Warning 523: Use of an illegal destructor name 'EStruct' in
%extend is deprecated, the destructor name should be 'tagEStruct'.
These %extend destructor and constructor names were valid up to swig-2.0.4, however swig-2.0.5 ignored
them altogether for C code as reported in SF bug #1306. The old behaviour of using them has been
restored for now, but is officially deprecated. This does not apply to anonymously defined typedef
classes/structs such as:
typedef struct {...} X;

When generating functions which wrap C extension code, use "(void)" for no-argument functions
instead of "()". This prevents warnings when compiling with "gcc -Wstrict-prototypes".

Deprecate typedef names used in %extend that are not the real class/struct name. For example:
