/* NOTES on rebuilding getdate.c (particularly for inclusion in CVS
   releases):

   We don't want to mess with all the portability hassles of alloca.
   In particular, most (all?) versions of bison will use alloca in
   their parser.  If bison works on your system (e.g. it should work
   with gcc), then go ahead and use it, but the more general solution
   is to use byacc instead of bison, which should generate a portable
   parser.  I played with adding "#define alloca dont_use_alloca", to
   give an error if the parser generator uses alloca (and thus detect
   unportable getdate.c's), but that seems to cause as many problems
   as it solves.  */
