Thanks, but please see my comments below.

This should have used xmalloc instead of calling malloc and checking
for errors.

I think this part is unnecessary. The old code didn't use
get_current_dir_name, so I think we should not introduce it now.
In any case, if we do introduce get_current_dir_name, we should add an
Autoconf test for it, and then use HAVE_GET_CURRENT_DIR instead of
_GNU_SOURCE (which I think is the wrong test anyway, btw: _GNU_SOURCE
has nothing to do with availability of certain library functions).

^^^^^^^
There's a typo in this line. Did you check that all the branches
actually compile?

You are using MAXPATHLEN without testing for it being defined. If it
is okay to assume that it is always defined, then why you introduced a
test for that in the first hunk of your changes (see above)?

Again, please use xmalloc.

And here too: please use xmalloc, and please resolve the MAXPATHLEN
issue.

The same comments apply there as well.
