No, it was this change:

2008-07-02  Laurent Michel  <address@hidden>

        * lightning/ppc/funcs.h (jit_flush_code): modified the computation
        of start/end. The pointer arithmetic was done without casting. It
        prevented compilation with recent gcc versions.

If you have time, I think syncing MzScheme's lightning now would not be
a bad idea.
