Well, so much for beta testers.  Everyone who got bibtex.c from me
or anywhere else, get the latest, via anonymous ftp, from:

	labrea.stanford.edu:~ftp/pub/bibtex.c.Z

There was a rather serious bug, which somehow didn't show up in the
test cases that were run.  (I don't use bibtex, so how was I to know?)
Anyway, the diffs are here, for those who don't have access to ftp:

<       if ( ( ( poplit1 <= 0 ) || ( poplit2 == 0 ) || ( poplit2 > exbuflength 
<       ) || ( poplit2 + (int) exbuflength < 0 ) ) ) exbuflength = 0 ; 
---
>       if ( ( ( poplit1 <= 0 ) || ( poplit2 == 0 ) || ( (int) exbuflength - poplit2
>       < 0 ) || ( poplit2 + (int) exbuflength < 0 ) ) ) exbuflength = 0 ;

<   tputs ( cnull , "This is BibTeX, C Version 0.98i\n" ) ;
---
>   tputs ( cnull , "This is BibTeX, C Version 0.98ib\n" ) ;

Note the renaming to 0.98ib.  As an aside, the bug illustrated by the
following code still exists in the VAX bsd 4.3 pcc compiler:

main() {
   int i = -1 ;
   unsigned short t = 44 ;

   if (i > (int)t)
      printf("Say what?\n") ;
}
