New complex patch for decrease size devel version. Requires previous patch.
Also removed small problems from dutmp and tar applets.
Also includes vodz' last_patch61_2:
Last patch correcting comment for #endif and more integrated
with libbb (very reduce size if used "cat" applet also).
Requires last_patch61 for modutils/config.in.
In most cases, dirname returns the same argument it was given, so this code
works nice, but there's one special case: when the name contains no
dirname, it returns "." (stored statically in the body of itself), and we
get a segfault in attempt to free() it.
This patch fixes this problem.
