Tue Oct  5 21:51:59 1993  Vern Paxson

       * Removed FILTER/ subdirectory.

       * Removed alloca.c.

       * Changed Makefile definition of CC to just "gcc -g", removed
         assumption of alloca being present.

       * Added pointer to MISC/fastwc/ to wc.lex.

Tue Jun  8 15:47:39 1993  Gavin Thomas Nicol  (nick at sillybugs)

       * Changed main() in wc.lex extensively. The old version would not
         work correctly without the YY_NEW_FILE. (lex handles the older
         version OK though).

       * Added a rule to expr.lex to handle whitespace. The old version
         reported an illegal character.

       * Added -traditional to the gcc flags because the flex definition
         for free() clashes with some systems that have old header files.
