[Scons-dev] SConstruct processing order

[Gary Oberbrunner]

There was a discussion of this a year or two ago.  Steven and I worked out
a scheme, but the part we got stuck on is that tools modify the
environment.  People expect, for instance, if they say
env.Append(CXXFLAGS='-xyz') that that will actually go at the end.  Making
that work if the tool hasn't set up its default CXXFLAGS yet seems very
difficult.
