* parse.y (trap_overflow_corner_case): New rule.
(unary_expression): Use it.
* lex.c (java_init_lex): Don't set minus_seen.
(yylex): Don't use minus_seen. Communicate overflow to parser for
it to handle.
(error_if_numeric_overflow): New function.
* parse.h (minus_seen): Removed field.
(JAVA_RADIX10_FLAG): New define.
