It uses to get an appropriate warning
in the case when the value is truncated.
sub_pattern_end if non-zero then we are parsing string which
should correspond compound specifier (like %T or
%r) and this parameter is pointer to place where
pointer to end of string matching this specifier
should be stored.
NOTE
Possibility to parse strings matching to patterns equivalent to compound
specifiers is mainly intended for use from inside of this function in
order to understand %T and %r conversion specifiers, so number of
conversion specifiers that can be used in such sub-patterns is limited.
Also most of checks are skipped in this case.
