* eval.c (language.h): Include.
* eval.c (evaluate_subexp_with_coercion): Only coerce arrays
to pointer types when the current language is C. It loses for
other languages when the lower index bound is nonzero.
* valarith.c (value_subscript): Take array lower bounds into
account when performing subscripting operations.
* valops.c (value_coerce_array): Add comment describing why
arrays with nonzero lower bounds are dealt with in value_subscript,
rather than in value_coerce_array.
