If I run Scons on the VS command line, Scons uses on env.Program the VS compiler (cl.exe), on the other hand if I run Scons from the MinGW shell, it uses also the cl.exe, but not the g++.exe. I can now overwrite the CXX / CC flag in the env, but why does Scons uses always the Visual Studio compiler? The PATH variable under MinGW shell does not have any path information to Visual Studio. IMHO I would like to detect and use under VS command line the VS compiler & linker (cl.exe & link.exe) and under MinGW shell the gcc / g++.

Go read the man page.
http://www.scons.org/doc/production/HTML/scons-man.html  (search for tool=)

Basically
Environment(tool=['mytool1','mytool2',…

You can see the list of tools in the man page as well.
