porting from 2.3 to 2.6.5

[Miquel Catala]

hello bison team

I have a software written for flex 2.5.35 and bison 2.3 that is now
working well in SLES11.1

I get many errors when trying to make it work in openSuSE 12.3.

...Rlex.L:42:8: error: 'YYSTYPE' does not name a type
...Rlex.L: In function 'int yylex()':
...Rlex.L:179:29: error: 't_DEBUG' was not declared in this scope
...Rlex.L:182:35: error: 't_PRINT' was not declared in this scope
...Rlex.L:186:6: error: 'yylval' was not declared in this scope
...Rlex.L:192:35: error: 't_LEFTCURLYBRACKET' was not declared in this
scope
...lex.L:194:6: error: 'yylval' was not declared in this scope
...Rlex.L:199:14: error: 't_RIGHTCURLYBRACKET' was not declared in this
scope
...

bison in openSuSE12.3 is 2.6.5.

Do you have any idea about what makes all those errors to raise??

thanks
