Thanks for info. Maybe a little note anywhere (e.g. commit message) would help.

Good point. So you plan to remove these build time checks?

Also we have nice docs from you include/tst_res_flags.h.
ATM include/tst_test.h and doc/old/C-Test-API.asciidoc are outdated,
but if you relax allowed ttype, than it would not need to be updated.

Also, any reason to not support TWARN?

I suppose we don't need TERRNO, TTERRNO, TRERRNO (not supported by tst_test.sh).

Anyway, LGTM.
