Hi Brad.

Users of GCC shouldn't have to wonder whether they should use the gcc
toolset (obvious; it's the name of the compiler like all the other
toolsets) or the darwin toolset (non-obvious: it's the name of the OS,
sorta, and it's not unlikely that we'll have toolsets for OSes someday
-- think cross-compilation). It's just confusing. I don't care how
the code is organized; this is a user-interface issue.

Take a good look at gcc.jam. It's already chock full of
platform-specific rules. Anyway, it wouldn't be hard to allow darwin
to be used as a toolset name transparently as a backward-compatibility
