Hi *,

FWIW: when /proc/self/exe exists it is a symlink to the currently
running executable, that should make the implementation of
find_executable() in these cases straight forward.

Basically:
  realpath ("/proc/self/exe", NULL);
should do the job.

/proc/self/run exists per default on most (all?) GNU/Linux Systems and
on my i386 NetBSD 9.1 per default.  In case of *BSD this might be a
Linux compatibility feature but I'm not sure -- needs checking.
