Ah, that's how you interpret it. I see, since the license in the header
files is akin to the "Old style" MIT (see
https://fedoraproject.org/wiki/Licensing:MIT?rd=Licensing/MIT#Old_Style ),
and MIT-alikes normally don't talk about the object code, there seem to be
a difference in interpretation of MIT and MIT-alike licenses as to whether
to include the license/notices with the binaries (Jonathan, the links are
included for someone who will stumble upon this post while searching; I
believe you know what I'm talking about and don't suggest you to sift
through them):

https://news.ycombinator.com/item?id=12560056
and so on. Both Chrome and Firefox (under windows) include MIT-licenses for
various libraries in their binary distributions and I saw one Huawei's PDF
also doing this (one of them was for STLPort: document "HUAWEI
ME906s-158&ME909s Series Module Open Source Software Notice" if anyone is
interested). As for myself I'm on the "'this software'/'copy' covers
derivative works/objective code"-side, but there doesn't seem to be any
authoritative source on this so we, indeed, go into "talk to your lawyer"
territory and I'm going to leave it at that.

Thank you for understanding what I was trying to say anyway - it was poor
wording on my part. As for the fourth one - imagine function declarations,
std::enable_if, something like factorial<4>::value in constexpr and so on:
things that usually don't result in a meaningful code generations by
themselves.

I started with this premise as well, but was met with "you only have to
follow GPLv3 + GCC Runtime Exception" view. Now that's settled, I have no
more questions; there seems to be only two possible conclusions:

a) If your interpretation is correct then the only license to follow with
binary distribution with dynamic linking is GPLv3+GRE;
b) If "this software" covers objective code, then the inclusion of HP/SGI's
copyrights and text is necessary.

Thank you for your time!
