	Thanks for the info. The problem I was trying to solve is this. SCons contains a built-in "tool detector" which, unfortunately, doesn't only look at paths and environment variables. On Windows, it also (I think) looks at the Windows registry. (I could be wrong about this...) Since I have 3 C++ compilers installed and use them all, this is no good. At any rate, by passing the tools to SCons programmatically, I defeat the tool auto-detection. We should look at the SCons source code to figure out a smarter way of doing this. Looking at the code could tell us how to turn a tool "off", which would get rid of cl in the MinGW build or g++ in the msvc build. Or, looking at the code could tell us just how to programatically set up the lex/yacc tools. Did you try just adding 'default' as a tool?...
