MSVC: lower C4100 warning level from 4 to 3

Browse Source 
This better aligns with OSX/Linux warnings.

Although `__pragma(warning(suppress:4100))` is not the same as
`__attribute__((__unused__))` in gcc (which only affects the attribute
instead of the line), it still seems to be better to use it than to
hide the warning entirely.
