For some reason I haven't seen your post on the newsgroup yet, did you get 
any message from the server when you sent it?

Yes - hence why I said:

Which is a crude but effective form of late identification (you identify 
what needs to be compiled at compile time based on what is available).  A 
better solution would be to get the list of things to compile from the SCM 
system, hence why I said:

Late identification is really the solution for Java too - but since the 
'Java' spec and compilers are rather fixed in their ways I suspect we just 
have to be pragmatic and do something that can support the 'broken' way they 
already work (there is no 'clearjavac' for good reason).  The ideal result 
would be  if a member of the Java compiler team wanted to add support for 
late identifiction - that'd be terrific!  It just takes a single call to an 
API to resolve every reference like eric.functional.Example into either 
eric.functional.Example (the default) or eric.test.TestExample etc based on 
rules the plugin used in the API knows about (eg: an SCM system that knows 
about the context/branch/usecase).  Chances of this happening I think are 
about equal to me winning the jackpot in the lottery when I don't actually 
buy a ticket...

All that said - the reason we had such a long discussion on c.s.config-mgmt 
about build was that the CM terminology and some of the reasoning behind 
'clearmake' and other commercial CM/build systems was not clear to me until 
you and some others explained it (which if you may recall took quite a lot 
of iterations), so I can't fault Gerhard or Eric or anyone else for not 
picking up on it.
