Bill,

Oh, yeah, and just to complicate the axiom build (since we're
shipping a packaged binary for windows) you should know that
axiom will run faster if you remove all of the .o files in
the obj subdirectory and redo the make.

What happens is that the first make will not only create the
compiled files but will also output the .fn files. These files
contain exact information about types used in function calling.
If the type information for foo.lisp (or foo.lsp) is available
at compile time and the foo.fn file is available from a previous
compile then the lisp compiler can lay down much more efficient
code for function calling. Since axiom is all about function 
calling this will make a significant difference in speed.
