Compile error with sip 6.7.10 - variable number of arguments

[Scott Talbert]

Hi Phil,

Sorry I didn't get a chance to test the prerelease of sip 6.7.10 with 
wxPython.  Unfortunately, I'm running into a compile issue with 6.7.10.

In file included from /usr/include/python3.11/Python.h:38,
                  from ../../../../sip/siplib/sip.h:24,
                  from ../../../../sip/cpp/sipAPI_core.h:13,
                  from ../../../../sip/cpp/sip_corecmodule.cpp:10:
../../../../sip/cpp/sip_corecmodule.cpp: In function ‘PyObject* 
func_LogInfo(PyObject*, PyObject*)’:

This error occurs in a function called wxLogInfo which is defined in a 
.sip file like this:

void wxLogInfo(
     const char * formatString,
     ...
);
%Docstring
     LogInfo(formatString, )

     For low priority messages.
%End

Looks like a1 got renamed but not completely?

Thanks,
