Fix clang build

The build failed with the following error:
non-constant-expression cannot be narrowed from type 'unsigned long' to
'uint32' (aka 'unsigned int') in initializer list [-Wc++11-narrowing]

This comes from the switch to C++11, the fix is to explicitely cast the
type (we know that it'll still fit into the smaller type).
