No clue; this involves a dark part of lilypond.

void
interpret_stencil_expression (SCM expr,
                              void (*func) (void *, SCM),
                              void *func_arg,
                              Offset o)
{

I've never seen the second argument for a C++ function.  I guess it's a
function pointer for a function which takes a void* and SCM?  Certain
when interpret_stencil_expression is called within lily/*.cc it's given
a void function.
