This file lists all bug fixes, changes, etc., made since the AWK book
was sent to the printers in August, 1987.
+Nov 29, 2002:
+ modified b.c (with tiny changes in main and run) to support
+ locales, using strcoll and iswhatever tests for posix character
+ classes. thanks to ruslan ermilov (ru@freebsd.org) for code.
+ the function isblank doesn't seem to have propagated to any
+ header file near me, so it's there explicitly. not properly
+ tested on non-ascii character sets by me.
+
+Jun 28, 2002:
+ modified run/format() and tran/getsval() to do a slightly better
+ job on using OFMT for output from print and CONVFMT for other
+ number->string conversions, as promised by posix and done by
+ gawk and mawk. there are still places where it doesn't work
+ right if CONVFMT is changed; by then the STR attribute of the
+ variable has been irrevocably set. thanks to arnold robbins for
+ code and examples.
+
+ fixed subtle bug in format that could get core dump. thanks to
+ Jaromir Dolecek <jdolecek@NetBSD.org> for finding and fixing.
+ minor cleanup in run.c / format() at the same time.
+
+ added some tests for null pointers to debugging printf's, which
+ were never intended for external consumption. thanks to dave
+ kerns (dkerns@lucent.com) for pointing this out.
+
+ GNU compatibility: an empty regexp matches anything (thanks to
+ dag-erling smorgrav, des@ofug.org). subject to reversion if
+ this does more harm than good.
+
+ pervasive small changes to make things more const-correct, as
+ reported by gcc's -Wwrite-strings. as it says in the gcc manual,
+ this may be more nuisance than useful. provoked by a suggestion
+ and code from arnaud desitter, arnaud@nimbus.geog.ox.ac.uk
+
+ minor documentation changes to note that this now compiles out
+ of the box on Mac OS X.
+

changed types in posix chars structure to quiet solaris cc.
