scons v4.3.0-1 outputs nothing on cygwin v2. 3.1

[Martin Ortuno]

Hi all,
Here the information you requested:

$ ls -glo /usr/bin/python

lrwxrwxrwx 1 13 Jun  3  2015 /usr/bin/python -> python2.7.exe



$ alternatives --display python

python - status is auto.

link currently points to /usr/bin/python3.9

/usr/bin/python3.9 - priority 39

Current `best' version is /usr/bin/python3.9.



$ cygcheck -c scons

Cygwin Package Information

Package              Version        Status

scons                4.3.0-1        OK



$ head -n1 /usr/bin/scons

#!/usr/bin/python3.9.exe

Thank you for your support...

Martin
