Browse Source 
gcc-6 has enabled more warnings by default, and turned some existing
warnings into errors.

Fixes (all on arc or arm):

lib/vterm_states: fix C++11 compliance
In C++11, narrowing a type is no longer allowed in structure
initializers:
struct foo { u16 u; };
foo f[] = { {0}, {-1} };
results in the gcc-6 to whine out loudly, and fail:
error: narrowing conversion of ‘-1’ from ‘int’ to ‘u16 {aka short unsigned int}’ inside { } [-Wnarrowing]
};
