Hi,
The attached patch deletes calls to strdup, strndup if it's
return-value is unused,
and same for realloc if the first arg is NULL.
Bootstrap+tested on x86_64-unknown-linux-gnu.
OK for GCC 8 ?
Thanks,

Hi Jeff,
Did you intend to approve the original patch (pr79697-1.txt) or the
latest one (pr79697-3.txt that also folds realloc (0, n) to malloc
(n)) ?
I was referring to the 3rd iteration. Sorry to have replied to the
first patch in the series -- my patches queue is a bit of a mess as
we're just getting started on gcc-8 stuff.
