Avoid warnings about comparisons being always true

Browse Source 
Depending on the signedness of length_t type we may either get
warnings comparison of unsigned expression in ‘>= 0’ being always true
or do insufficient checking by not checking if index is not negative.

Hide the index checking behind a macro that check the index properly.
