# WinFlexBison - Flex and Bison for Microsoft Windows

WinFlexBison is a Windows port of [Flex (the fast lexical analyser)](https://github.com/westes/flex/) and [GNU Bison (parser generator)](https://www.gnu.org/software/bison/).

Both win_flex and win_bison are based on upstream sources but depend on system libraries only.

**NOTE**:

* 2.4.x versions include GNU Bison version 2.7

* 2.5.x versions include GNU Bison version 3.x.x
