OK.  There's an implied "and put back have_atexit".

Please apply these patches:

	* sco5.h: revert previous change.  The cost of picking up
	  more code from libgcc2 exceeds the cost of p9732b.C having
	  static destructors that call exit calling abort.

	* p9732b.C: Don't call exit from static destructors. Since
	we may be calling them via atexit, we want to avoid cleanup
	recursion.

> Shouldn't OpenServer COFF also define HAVE_ATEXIT?


Morally, yes, it should.

Even though it is, at that point, a COFF target, it still
has a _fini section that gets registered to execute via 
atexit().  

$ file crtendS.o ; dis crtendS.o | tail
crtendS.o:      iAPX 386 COFF object file not stripped - version 30821
          2b:  90                     nop

section .fini
.fini
__DTOR_END__
          2c:  00 00                  addb   %al,(%eax)
          2e:  00 00                  addb   %al,(%eax)
__FRAME_END__
          30:  00 00                  addb   %al,(%eax)
          32:  00 00                  addb   %al,(%eax)


As you can see, we are going to try to execute this (after we've done
all our destructors which is done first) we're headed for a SIGILL.

Can you help me untangle the right combination to get a useful
binary?  Between crtstuff.c and gbl-ctors.h and all the preprocessor
voodoo going on, I can't grok it.   There is much voodoo at the end 
of sco5.h to try to outsmart all the voodoo in the other two files.
I spent many hours on this when I first did it and just decide to 
punt this issue and let COFF not use ATEXIT.
