[Flex-devel] yytext and similar in -P scanners

[Petr M. <pma...@re...>]

Hi list,

the editor `vile' (aka "vi like emacs") currently fails to build with
new flex, i.e. flex post 2.5.4a.  The problem is that in scanners
generated with -P, symbols yytext, yyleng, yylineno and others are not
available.  Documentation states that they should be:

> Within your scanner itself, you can still refer to the global
> variables and functions using either version of their name; but
> externally, they have the modified name.

I'm sending the patch that should fix this problem.  It does the same
thing old flex does, namely it introduces #defines for yy symbols.

Comments welcome.

Thanks,
PM
