Tried all the options, varing w/wo "-m". Not much exciting.

Current version is

Curiosily, compiling Analysis.py with 
# Analysis.py
import os
import sys

print('test')
blabla

(so obviously it should not compile), returns no error

gprbuild -ws -c -f -u -PP:\Gnat\testpy.gpr Analysis.py
Compile
   [python]       analysis.py
[2022-11-11 18:27:03] process terminated successfully, elapsed time: 03.58s

But no problem. I'm convinced that Python (as external code, not GPS internal 
script) should be kept very far from GPS. 

Thanks!
