! 232: ** more portability fixes around how we get ahold of the integral
! 233: types; there is a constant FLEX_NEED_INTEGRAL_TYPE_DEFINITIONS
! 234: which you should define if you don't have the <inttypes.h> header
! 235: file (after you complain to your C vendor for not providing a

! 427: ** configure now uses autoconf's versioning information and configure
! 428: --help reports the bug-reporting address for flex
! 429:
! 430: ** test suite now only reports success versus failure; reporting
! 431: skipped is problematic under the current setup
! 432:
! 433: ** compilation with --disable-nls now works

! 468: options, see accompanying documentation
! 469:

! 492:
! 493: *** Added get/set functions for members of struct yy_globals_t
! 494: e.g., yyget_text, yyget_leng, etc

! 504: But the inverse is still true
! 505:
! 506: ** Developer test suite added
