There was some thought to using the crti.c that Don Terry mentioned.  Even
though they're tiny, the thought of having (at least) three files doing 
the same thing seems sort of icky.

Right.  This was the piece missing in your original patch.

You can decide whether or not to include it in COFF builds (please be
sure to test it if you do).  I don't immediately see the harm in it.
