Yes, that's the required behavior.  N1570 7.22.1.4p8:
"""
The strtol, strtoll, strtoul, and strtoull functions return the
converted value, if any. If no conversion could be performed, zero is
returned. If the correct value is outside the range of representable
values, LONG_MIN, LONG_MAX, LLONG_MIN, LLONG_MAX, ULONG_MAX, or
ULLONG_MAX is returned (according to the return type and sign of the
value, if any), and the value of the macro ERANGE is stored in errno.
"""

N3220 has identical wording in 7.24.1.7p8.  The wording for strtoimax
and strtoumax (<inttypes.h>) is equivalent.
