... and a bug report: SIP generates a sipFree() call to free the wchar_t 
memory after having used it. It works if the pointer is of type 
"wchar_t*", but it does not work if the pointer is of type "const wchar_t*":

error C2664: 'void (void *)' : cannot convert parameter 1 from 'const 
wchar_t *' to 'void *'
         Conversion loses qualifiers

I worked around it by dropping the const qualifiers from the parameter 
declarations in the SIP files.
