So it is possible that the change which does the damage is the one about 
.got sections, not the fact that file I/O is used instead of mmap.  Could 
you try unexelf.c from v21.2 with the .got sections and see if that makes 
Emacs 21.1 unable to print?

David, can you help us here and explain why those additions were 
necessary?  Perhaps the new unexelf.c in Emacs 21.2 makes them redundant?

To fill you in, this thread (which you can find on gnu.emacs.bug) was 
about "emacs -batch" being unable to print to stdout when compiled with 
GCC.  Ralf's debugging indicates that this happens because fwrite somehow 
fails to allocate the buffer for the FILE object (this is in part a 
speculation, since we don't have access to library sources).

Also, do you have any clue why does the problem happen with GCC, but not 
with the native compiler?

TIA
