I noticed that YaST prints garbage when the logfile cannot be
opened. The problem is that strerror_r may leave buf untouched so
you have to print the returned pointer (when using the GNU
version of strerror_r).

patch looks fine. Just I am curious if there is agreement that yast
code is GNU specific. If we want more portable code ( for whatever
reason ) maybe it will be better to just undef _GNU_SOURCE there.

Well, currently several GNU specific functions are used
(e.g. asprintf, basename, canonicalize_file_name). Apart from
that g++ already defines _GNU_SOURCE so making sure that no GNU
specific functions are used is not easy or maybe even impossible
(without another compiler).

what comes to my mind is potential usage of icc or llvm for
compilation, where we can have problems.
If we really want GNU version we should ensure, that it is used with
preprocessor magic.
Example is e.g. in this header file with defining and undefining

So question is if we want be prepared for different compiler and
different libc ( like uclibc or dietlibc ). But quick research show that
uclibc with proper directory can use gnu extension and dietlibc start
having some gnu extensions, so maybe it is not so big issue. I just
think that we should explicitelly state this somewhere to avoid
