Sorry, premature send. Here's more info:

The projects look like this:

ex.c/ex.cpp:
#include <stdio.h>
#include "ex.h"

int main() { prt(); return 0; }

ex.h:
static void prt() { printf("prt from c\n"); }

Attached are logs generated by running 'bjam -d3' in each project 
directory after touching ex.h.
