    Explicitly cast tolower() return value to char before storing in a char
    
    For ancient historical compatibility, the C standards define the
    <ctype.h> functions as taking & returning ints, but limiting them
    to the subset of values that fit in a char.
    
    Silences clang warning:
    xkill.c:244:12: warning: implicit conversion loses integer precision: 'int' to
          'char' [-Wconversion]
                *cp = _tolower (*cp);
                    ~ ^~~~~~~~~~~~~~

    Mark arguments to catch_window_errors as unused
    
    Arguments are required by the callback form, but not needed in this case.
    
    Clears clang compliants:
    xkill.c:328:30: warning: unused parameter 'dpy' [-Wunused-parameter]
    catch_window_errors(Display *dpy, XErrorEvent *ev)
                                 ^
    xkill.c:328:48: warning: unused parameter 'ev' [-Wunused-parameter]
    catch_window_errors(Display *dpy, XErrorEvent *ev)
