This file lists all bug fixes, changes, etc., made since the AWK book
was sent to the printers in August, 1987.
+Feb 10, 2002:
+ changed types in posix chars structure to quiet solaris cc.
+
+Jan 1, 2002:
+ fflush() or fflush("") flushes all files and pipes.
+
+ length(arrayname) returns number of elements; thanks to
+ arnold robbins for suggestion.
+
+ added a makefile.win to make it easier to build on windows.
+ based on dan allen's buildwin.bat.
+
+Nov 16, 2001:
+ added support for posix character class names like [:digit:],
+ which are not exactly shorter than [0-9] and perhaps no more
+ portable. thanks to dag-erling smorgrav for code.
+
+Feb 16, 2001:
+ removed -m option; no longer needed, and it was actually
+ broken (noted thanks to volker kiefel).
+
+Feb 10, 2001:
+ fixed an appalling bug in gettok: any sequence of digits, +,-, E, e,
+ and period was accepted as a valid number if it started with a period.
+ this would never have happened with the lex version.
+
+ other 1-character botches, now fixed, include a bare $ and a
+ bare " at the end of the input.
+
+Feb 7, 2001:
+ more (const char *) casts in b.c and tran.c to silence warnings.
+
Nov 15, 2000:
fixed a bug introduced in august 1997 that caused expressions
like $f[1] to be syntax errors. thanks to arnold robbins for
