   Apr 16, 1999:
           with code kindly provided by Bruce Lilly, awk now parses
           /=/ and similar constructs more sensibly in more places.
   
   Apr 5, 1999:
           changed true/false to True/False in run.c to make it
           easier to compile with C++.  Added some casts on malloc
           and realloc to be honest about casts; ditto.  changed
           ltype int to long in struct rrow to reduce some 64-bit
           complaints; other changes scattered throughout for the
           same purpose.  thanks to Nelson Beebe for these portability
           improvements.
   
           removed some horrible pointer-int casting in b.c and elsewhere
           by adding ptoi and itonp to localize the casts, which are
           all benign.  fixed one incipient bug that showed up on sgi
           in 64-bit mode.
   
           reset lineno for new source file; include filename in error
           message.  also fixed line number error in continuation lines.
           (thanks to Nelson Beebe for both of these.)
   
   Mar 24, 1999:
           Nelson Beebe notes that irix 5.3 yacc dies with a bogus
           error; use a newer version or switch to bison, since sgi
           is unlikely to fix it.
