We noticed that icc does use other values for LDBL_MIN than we do, and
instead of just thinking that Intel does it right I wanted to verify it.
So I started with tests for float and double.

*_MIN _is_ the smallest positive value... but the normalized one, not
the denormalized one I use. So yes, my program was wrong, but in another
way than you suggested. But I have to still say "thank you", your
comment resulted in rereading the (hopefully) appropriate docs and
noticing the "normalized" in them.
Thank you,
Alexander.
