targets in the build system able to be run successfully)
* version 2.5.31 released 2003-4-1
** remove --enable-maintainer-mode configure option; none of the
Makefiles were using it and it can be unduely confusing
* version 2.5.30 released 2003-4-1
** yylineno is per-buffer in reentrant scanners
** added %top directive for placing code at the top of the generated
scanner; see manual for details

** flex now warns about pattern ranges that might be ambiguous when
generating a case-insensitive scanner
* version 2.5.25 released 2002-12-2
** flex now uses flex_int*_t types. For C99 systems, they are just the
int*_t types; for non-C99 systems, we just make some typedefs
** new pt_br translation from the translation project
* version 2.5.24 released 2002-11-25
* more portability fixes
** the manual continues to be updated and edited, but it's still got a

should have been
* version 2.5.22 released 2002-10-10
** more portability fixes around how we get ahold of the integral
types; there is a constant FLEX_NEED_INTEGRAL_TYPE_DEFINITIONS
which you should define if you don't have the <inttypes.h> header
file (after you complain to your C vendor for not providing a
reasonable C environment)
** more test suite cleanups; in particular, the test suite should run
correctly when build from a different directory
** upgraded automake to 1.7 and consequently autoconf to 2.54; this
means, among other things, that there is some support for
formatting the manual in postscript and pdf in the distributed
Makefile.in (and therefore in the Makefile built by configure)
** the flex.1 manpage is generated by help2man; (this has been true
for quite a while but was not listed here)
** flex now includes three defined constants to indicate which version
of flex generated a scanner (YY_FLEX_{MAJOR,MINOR,SUBMINOR}_VERSION)
** flex tries its best to output only the relevant portions of the
skeleton when generating a scanner, thus avoiding as much
conditional compilation as possible
* version 2.5.21 released 2002-9-17
** one of the tests in the test suite broke the dist target
* version 2.5.20 released 2002-9-16

and load them at runtime when needed; see the manual for details
** Added %option bison-bridge (--bison-bridge)
** Removed %option reentrant-bison/--reentrant-bison/-Rb
** yylineno is present in all scanners; Modified nasty performance
penalty warning with yylineno in documentation
** test-table-opts is now run last in the test suite because it's so fat
** flex can, to some extent, diagnose where internal problems occur

manual if that's not a good thing for you
* version 2.5.19 released 2002-9-5
** prevent segfault on input lines which are longer than the allocated
space (problem report from Manoj Srivastava
<srivasta@golden-gryphon.com>)
** Changed option 'header' to 'header-file'
* version 2.5.18 released 2002-9-4
** portability fixes for integer constants and in the way the test
suite reports its results
** the test for bison was reporting bison missing when it was, in
fact, found
** if we don't find GNU indent, we're more careful when we're not
finding it
* version 2.5.17 released 2002-8-29
** more portability fixes
** updated config.sub and config.guess
** flex is indented by GNU indent (this was done earlier but not
explicitly documented)
* version 2.5.16 released 2002-8-28
** c++ scanners compile again
** there is now an indent target in the top-level Makefile; configure
checks for GNU indent which is required for proper operation of the
indent target

** %options and invocation sections of manual merged
** a c++ test was added to the test suite
** we're trying to clean up more files in the test suite's make clean
targets
* version 2.5.15 released 2002-8-21
** reject-state buffer is now dynamically allocated and REJECT buffer
variables are reentrant-safe
** manual now discusses memory usage
** skeleton now processed by m4 before mkskel.sh; (this only matters
if you want to change the skeleton or if you're doing flex development)
** zh_cn translation added from translation project
** a bug that caused a segfault has now been fixed
** the test suite now respects the usual CFLAGS, etc. variables
** removed some warnings which some tests trigggered with the -s option
** the flex-generated header file now tries to be smarter about
conditionally including start conditions
** tables code omitted from generated scanner when not used
* version 2.5.14 released 2002-8-15
** the tests using the reentrant c scanner as c++ were reworked
slightly to be sure that the c++ was enforced
** de translation now included in the distribution
** various portability fixes regarding nls support, c++ include
headers, etc.
* version 2.5.13 released 2002-8-15
** the header file output with %option header is now much smaller
** Fixed type mismatch in printf in scanner skeleton
** yylex_init now reports errors
* version 2.5.12 released 2002-8-8
** updated gettext support to 0.11.5
** new fr translation from the translation project
** bison is no longer needed to build flex; If you are building flex
from a release (i.e., not from a cvs snapshot), then you don't need
to have a pre-built lex around either (unless you modify scan.l, of
course); (This has been true for some time, but was not mentioned
here.)
* version 2.5.11 released 2002-7-31
** Fixed bug where yyless did not consider yylineno
** the yylineno performance hit is now gone
** fixed some typos in the manual and we now include texinfo.tex in

preprocessor symbol; see documentation for details
* version 2.5.10 released 2002-7-24

yy_guts_t

** new tests in test suite: test-mem-{nr,r}, test-posix,
test-posixly-correct, test-debug-{nr,r}
** made changes to work with gcc-3.2 development code
** ability to choose which memory functions are used in flex

** new handling of POSIXLY_CORRECT environment variable
** the test suite now has its copyrights explicitly described
** new ca, de, fr, ru, sv, tr translations
* version 2.5.8
** a new --posix option generates scanners with posix-style abc{1,3}
compatible parsing, see manual for the screwy details
* version 2.5.7
** configure.in now includes a call to AC_PREREQ to enforce the
requirement for autoconf at least 2.50 (This only effects you if
you're doing flex development.)
** configure now uses autoconf's versioning information and configure
--help reports the bug-reporting address for flex
** test suite now only reports success versus failure; reporting
skipped is problematic under the current setup
** compilation with --disable-nls now works
** flex can now be built in a separate directory
* version 2.5.6
** gettext support added (from gettext 0.11)
*** translations for ca, da, de, es, fr, ko, ru, sv, tr included

*** --yyclass=NAME name of C++ class when generating c++ scanners
*** for long option names which are associated with existing short
options, see accompanying documentation
*** new %option nounistd or command-line --nounistd added to prevent
flex from generating #include <unistd.h> on systems that don't
have that include file
** Support for reentrant C scanners has been added
*** Updated the manual with the new reentrant API
*** Two new options %option reentrant (-R) and
%option reentrant-bison (-Rb)
*** All globals optionally placed into struct yyglobals_t
*** All access to globals replaced by macro invocations
*** All functions optionally take one additional
argument, yy_globals
*** New style for invoking reentrant scanner:
yylex_init(void** scanner );
yylex( scanner );
yylex_destroy( scanner );
*** Added get/set functions for members of struct yy_globals_t
e.g., yyget_text, yyget_leng, etc
*** Prefix substitution added for new functions
*** Macro shortcuts to the lengthy get/set functions
provided for use in actions, e.g., yytext, yyleng, etc
*** Arbitrary, user-defined data, "yyextra", may be added to scanner
** %option nomain no longer implies %option yywrap
But the inverse is still true
