so update this to version nawk-20020628.
Changes: (note credit to jdolecek :)
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,
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.
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.
