Hi Takashi,

I just tripped over a small problem with gobject-introspection:

This fails because the _giscanner module is built for (and linked 
against) python3.9.


I don't quite understand why this is happening since we configure with 
"-Dpython=${PYTHON3}", so I'd expect end up with the full path to 
specific python version in the shebang line in g-ir-scanner.

(I think that's what was happening before upstream switched from 
autotools to meson)

In any case, this can be fixed in the cygport by using 
python3_fix_shebang on this script.
