The compiler doesn't perform the `load/use-compiled's when it compiles
the main file. Instead, it just compiles each `load/use-compiled'
expression. Consequently, the macro `set-matrix4' is not defined when
the compiler processes the rest of the file.

In version 199.X, the solution is to use `module'.

In version 103.X, the solution is more clumsy; add a
`begin-elaboration-time' load for every file that defines both macros
and values:

  (load/use-compiled (build-path "matrix4.scm"))
  (begin-elaboration-time (load/use-compiled (build-path "matrix4.scm")))
