I'm sorry I forget to tell you I reverted this, it was deliberate change.
Using TST_NO_DEFAULT_MAIN was wrong (it's usually used in LTP library only.
Also it's recommended to use SAFE_*() if possible.

I've sent patch to implement this for some C code [1], but it's failing (endless clone).

Kind regards,
Petr
