This file lists all bug fixes, changes, etc., made since the AWK book
was sent to the printers in August, 1987.
Jun 7, 2018:
(yes, a long layoff)
Updated some broken tests (beebe.tar, T.lilly)
[thanks to Arnold Robbins]
Mar 26, 2015:
buffer overflow in error reporting; thanks to tobias ulmer
and john-mark gurney for spotting it and the fix.
Feb 4, 2013:
cleaned up a handful of tests that didn't seem to actually
test for correct behavior: T.latin1, T.gawk.
Jan 5, 2013:
added ,NULL initializer to static Cells in run.c; not really
needed but cleaner. Thanks to Michael Bombardieri.
Dec 20, 2012:
fiddled makefile to get correct yacc and bison flags. pick yacc
(linux) or bison (mac) as necessary.
