classical error but unresolved "syntax error at end of input"

[DEBUF Xavier]

the result of the grammar file (*.y) compilation give me this error:
"syntax error at end of input"

I Know this is not really important but i don't find it and I can't test
my grammar file I give you the code (begin and end of it)

A warning appear to indicate that yyerror has been declared on implicit
way "Static" and farrer "extern" I really don't know what is the meaning
and if it's important or not...

thanks for your help
