It's been a while, but from the top of my head, here's what's new in Flex:


* Reentrant scanner.
* User-supplied memory management.
* Tables may be loaded/unloaded on the fly, from disk/network,etc.
* Generated C header file as well as C file.
* Bison integration (yylloc/yylval support).
* yylineno optimized.
* Numerous bug fixes.
* Regression test suite.
* texinfo manual.
* FAQ built from years of email Vern collected.


We took extreme pains and much of our time to please the unplacable, to
answer to the cries of incompatibility with DOS, pre-ANSI C, and OS's without
fork, as well as the dubious perspective that scanners and parsers should be
cleaved apart, ne'er to embrace one another. As such, the scanner skeleton is
mangled beyond recognition, so that it may be demangled by the likes of `m4`,
flex's preprocessor, and eventually the C preprocessor.
