The copy of the modules set up by `mzc --c-mods' preserves the modules
original collection-based paths, so you can `require' the embedded
modules as if they were still installed as a collection.

After calling declare_modules(), the simplest way to `require' the
module `mzlib/defmacro' into the current namespace is to use
scheme_namespace_require(), like this:

  scheme_namespace_require(scheme_intern_symbol("mzlib/defmacro"))

which is the same as the call

  (namespace-require 'mzlib/defmacro)

in Scheme.
