That warning is a diagnostic message about a constraint violation.
It is not optional. (I personally consider it unfortunate that gcc
chooses to issue non-fatal warnings for some constraint violations,
but that can be worked around using the "-pedantic-errors" option.)
In C99 and C11, declaring the type of a variable is not optional.
A program that fails to do so is just as invalid as a program
containing a syntax error. gcc's odd way of diagnosing such errors
is not a language issue (except for the fact that the C standard
permits such treatment).
