* version 2.5.6
** command-line option parsing happens differently now:
*** Added long option parsing
*** Options -n and -c, previously deprecated, now simply do nothing
*** Options are now parsed left to right
** added a number of new options
*** All positive %options are now accessible from the command line
*** Added option -D, to define a preprocessor symbol.
*** Added option --header=FILE to specify a C .h file to generate.
*** added option --yywrap to call yywrap on EOF
*** added option --yylineno to track line count in yylineno
*** --yyclass=NAME name of C++ class when generating c++ scanners
*** for long option names which are associated with existing short
options, see accompanying documentation
** 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.
** Developer test suite added.
*** TESTS/ directory has been added. Users can
'make check' in the TESTS directory to execute the test suite.
** Support for bison variables yylval and yylloc added.
** automake support for the build process
** manual is now in texinfo/info format
*** flex.1 removed from distribution
** flex no longer generates C-language scanners with C++-style
comments
** flex now generates scanners in c++ which are compatible with
recent c++ compilers
** flex input scanner now recognizes '\r' as an EOL character
