Hi Reid,

Sorry I can't go into as much detail as your question did right now, but
basically:
 
1) We don't have an "install" target because we haven't yet needed one.
   There's nothing wrong with writing one up.
 
2) Moving all our header files into the include/llvm/ directory, and merging
   include/Support and include/llvm/Support, are both good ideas as well,
   though it will take careful work to make sure that nothing breaks.
 
3) The .o files are used when we want to link all objects from a particular
   library in to a tool, e.g., opt, which needs to link in all optimizations,
   even those which it does not explicitly reference. There's nothing
   wrong with building .a versions of all libraries, we just don't do that
   right now. Check out the Makefile.rules BUILD_ARCHIVE option.

4) The GNU linker is very, very slow, mostly because it has not been tuned
   for performance by its developers.  Some improvements may be forthcoming
   in the current CVS version of binutils; you may want to try it out.

-Brian
