We don't want another commit after every other commit.  This should be  
set by the makefile when a build is done.

I don't see what that has to do with anything here.  Have you build  
llvm-gcc lately?  It says that for every build - it *is* based on  
apple gcc.

This isn't a commit, it's just a file that's not under version
control
but created during update/checkout.

I suppose to be annoyingly pedantic about it you could require a  
network connection for the build, check svn info and svn status and  
then set the version string based on whether or not there are local  
patches applied to the checkout - but that would probably fall under  
neurotic :)

Using svnversion (as the original patch does) does exactly this. It outputs
the rev number, postfixed with "M" (for Modified) when there are local
changes.

This does not require a network connection, however, svn keeps a local clean
copy of everything (as opposed to CVS).
