Miscellaneous flex stuff. The following have been tested using flex 2.4: - debflex.awk, an awk script for anotating flex debug output. It presently only works with gawk, not with "old" or "new" awk (I haven't tried "mawk"). - testxxLexer.l, a sample C++ program that uses flex's scanner class option ("-+"). - fastwc/, a subdirectory containing examples of how to use flex to write progressively higher-performance versions of the Unix "wc" utility. The following are all out-of-date with respect to flex release 2.4 (and in general up-to-date for flex 2.3): - flex.texinfo, a "texinfo" version of the flexdoc documentation for flex release 2.3. - Atari/Atari.patches, patches for porting flex to the Atari and to Minix. - A number of notes and Makefiles for compiling flex under MS-DOS, in the MSDOS/ subdirectory. - Notes on building flex for MVS, in the MVS/ subdirectory. - Notes on building flex for the Macintosh using Think-C, in the Think-C/ subdirectory. - Notes on building flex for VMS, in the VMS/ subdirectory. And the following is included for compatibility with some broken versions of bison: - alloca.c, a public-domain, mostly-portable version of the alloca() routine (used by bison's parsers) written by D. A. Gwyn. Many thanks to those who contributed these files. Updated versions will be appreciated!
