I for one would love to have dependencies in my extension modules, I
usually end up deleting the build directory whenever I've changed a header
file :(

How about something like this:

  Extension('foo', ['foo1.c', 'foo2.c'], dependencies={'foo1.c':
  ['bar.h'], 'foo2.c': ['bar.h', 'bar2.h']})

though there is the problem of backwards compatability :/


Just my two cents,
Martin
