Having read the rest of this thread so far, I suggest that you put your
built-in functions into a module which can then be loaded by your pure
Scheme functions.
You need to do something like this:
static SCM
my_func (SCM arg)
{
/* ... blah blah ... */
}
static void
init_builtins_module ()
{
scm_c_define_gsubr ("my-func", 1, 0, 0, my_func);
scm_c_export ("my-func", NULL);
}
void
init_builtins ()
{
scm_c_define_module ("myapp builtins",
init_builtins_module,
NULL);
}
Then in your pure Scheme module, you can add:
(use-modules (myapp builtins))
I hope that helps.

Peter
