* data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,

Emphasize that yylex and yyerror must be declared before being used.
E.g., one should typically declare them in the prologue. Use GNU
coding style in examples. Put "const" consistently after the type it
modifies. Mention that C99 supports "inline". Mention that yyerror
traditionally returns "int".
