Build error: btSoftBodyHelpers.cpp + clang3.2: -Wc++11-narrowing

Building bullet-2.81-rev2613.tgz on travis-ci.org (debian based Linux) using 
clang++ --std=c++11

What is the expected output? What do you see instead?
bullet sdk builds.

Instead I get the following:

Please provide any additional information below.
As given by clang, the fix is easy. Just wrap the values in a 
static_cast<int>() (patch file provided).
