    Redefine ZERO_OBJ() to use memset(). · 71fdcc3b
    Geoff Simmons authored
    Newer versions of the compilers have apparently set the source level
    switches differently, so that explicit_bzero() is not defined as our
    source is currently written. The autoconf AC_CHECK_FUNCS check
    evidently sets certain source switches, but is not transparent
    about which ones (this has become evident with strdup() as well).
    
    On my machine, right now, defining _DEFAULT_SOURCE appears to do
    the trick. But it is not obvious what else that turns on and off.
    
    It is poor practice to cargo-cultishly turn on GNU_SOURCE for
    everything. That risks portability and compatibility, and may make
    us unwittingly dependent on non-standard features that may or may
    not be supported elsewhere.
    
    Besides, we only need ZERO_OBJ() for FREE_OBJ(), it frankly doesn't
    matter much if we zero an object whose pointer is about to be free'd.
