This presumes that every platform has bzero, which is unsafe (POSIX
doesn't specify it) and is an assumption we kicked to the curb a dozen
years ago (067a5cdb3). Please use memset() for the substitute instead.
Also, I'm a bit suspicious of using AC_CHECK_FUNCS for this; that
generally Doesn't Work for anything that's not a vanilla out-of-line
function. Are we worried about people implementing this as a macro,
compiler built-in, etc?
