Message:

libc-0.6: system() and popen() should use the same shells, preferablly /bin/sh when available (see unix spec). arg[0] shouldn't have a path, according to unix tradition (should be 'sh' to be more precise). Introduced a backend API for finding the desired shell and figure arguments. Fixes #287.
