How to use different yylex ?

[Timothy Madden]

Hello

All symbols generated by bison atr included in the yy:: namespace (in 
the yy::parser class actually), except the yylex function.

Is there a way to change the name for yylex function ? So it does not 
have to be a global function ? Or even a way to use yylex() method on an 
object of class yyFlexLexer ? Other than using #define yylex, which I 
think is not very friendly ?

Thank you,
Timothy Madden
