Log:
Fix gcc build
We have -Werror=strict-overflow so gcc complains:
In file included from
/tmp/obj/workspace/src/amd64.amd64/tmp/usr/include/bitstring.h:36:0,
from /workspace/src/tests/sys/sys/bitstring_test.c:34:
/workspace/src/tests/sys/sys/bitstring_test.c: In function 'bit_ffc_at_test':
/workspace/src/sys/sys/bitstring.h:239:5: error: assuming signed overflow
does not occur when assuming that (X + c) >= X is always true
[-Werror=strict-overflow]
if (_start >= _nbits) {
^
Disable assuming overflow of signed integer will never happen by specifying
-fno-strict-overflow
