Update to 1.2.0

  Due to incompatibilities between traditional BSD mk files and mk
  files shipped with bmake by Simon J. Gerraty, I've decided to switch
  runawk from BSD mk files to mk-configure software build system. This
  makes Makefile significantly smaller, easier to understand and use
  and gives tons of new capabilities. Obviously this makes development
  even easier than before. Updated installation instruction is in
  README.

  New functions in heapsort.awk: "heapsort_fields" and \ 
"heapsort0" for
  sorting $1, $2 ...

  New function in tokenre.awk: "splitre".

  New samples of use (regression tests):
    examples/demo_tokenre4, demo_heapsort4.
