William,

thanks, but I believe that only addresses some of my concerns. I also
found your answer to a similar question here:
http://scons.tigris.org/ds/viewMessage.do?dsForumId=1272&dsMessageId=2927425,
which is helpful, but not quite complete (as it isn't clear what other
variables specifically need to be changed, and how. Can you point me to
some documentation that explains how the various compiler-related
variables are defined, so I know what exactly I need to redefine to be
able to switch toolchains on the command-line ?

Also, any insights into the other question:

Thanks,
