I slightly prefer tst_res(TINFO, "WARNING: ...", than TWARN. Although false
negative is serious, still failing the test based on suspicion of false
positives is not good.

@Li, @Jan, @Metan: any opinion on it?

Also, I send a patch to add TINFO_WARN flag (yeah, ugly name) to print TINFO
but slightly more visible due the color.
