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++.

I know the tool option, but how I can change the compiler search list? Should I rewrite the full tool list in the dependcy of my environment?
