Version 1.3.39 (in progress)
============================
2008-02-12: wsfulton
Remove unnecessary temporary variable when wrapping return values that are references.
Example of generated code for wrapping:
struct XYZ {
std::string& refReturn();
};
used to be:
std::string *result = 0 ;
...
{
std::string &_result_ref = (arg1)->refReturn();
result = (std::string *) &_result_ref;
}
Now it is:
std::string *result = 0 ;
...
result = (std::string *) &(arg1)->refReturn();

Change the SIZE mapped by %pybuffer_mutable_binary and %pybuffer_binary in pybuffer.i from
the length of the buffer to the number of items in the buffer.
