I don't know the details of the first patch, but I believe I added the 
following lines to config/go32.h.  Your mention of HAVE_ATEXIT just
makes we worried I may have overlooked something when I did this last 
April-ish.

/* djgpp has atexit ().  */
#undef HAVE_ATEXIT
#define HAVE_ATEXIT

/* djgpp automatically calls it's own version of __main, so don't define one
   in libgcc, nor call one in main().  */
#define HAS_INIT_SECTION

typhoon:gcc$ patch < elipatch.diff
patching file `libgcc2.c'
Hunk #1 succeeded at 1688 (offset 77 lines).
typhoon:gcc$ emacs libgcc2.c
typhoon:gcc$

Looks OK (this was against the pgcc 1008 sources).  
Remember to send to the egcs list too, as well as gcc2
(or I could do this if you want).
