This DR was already resolved for GCC 7.1 by the implementation of DR 2192, but we didn't have an explicit test for the behaviour that 2735 guarantees. * doc/xml/manual/intro.xml: Document LWG 2735 status. * include/bits/std_abs.h: Add comment about LWG 2735. * testsuite/26_numerics/headers/cstdlib/dr2735.cc: New test.
