Macros?

SWIG_VERSION is a hexadecimal integer such as 0x010311 (corresponding to
SWIG-1.3.11).

#if SWIG_VERSION < 0x040300
   // Swig before 4.3.0
#else
  // Swig at 4.3.0 and above
#endif

<br>
We ran into some build issues with the latest SWIG master (4.3.0)=C2=A0 - w=
hich removes t_output_helper. <br>
<br>
I&#39;ve updated the code as suggested in the release notes by using SWIG_P=
ython_AppendOutput. See <a href=3D"https://github.com/MapServer/MapServer/p=
ull/7083/files" rel=3D"noreferrer" target=3D"_blank">https://github.com/Map=
Server/MapServer/pull/7083/files</a><br>
<br>
Is there a way to make this change compatible with both 4.3.0 and previous =
4.x SWIG builds?<br>
<br>
SWIG_Python_AppendOutput expects a new $is_void parameter in 4.3.0 but won&=
#39;t build in previous versions when added, e.g. SWIG_Python_AppendOutput(=
$result,r,1);<br>
<br>
Thanks for any hints,<br>
<br>
