The question "which platforms support a given interface?" is, I think, best
answered by the symbols x platforms matrix that I'm maintaining at
  http://www.haible.de/bruno/gnu/various-symlists.tar.gz

Feel free to provide updates to me; also feel free to provide a other
interfaces to it (such as automatically generated .texi docs) if you want.

So, I agree with you that this info is important for some decisions people
want to make. But OTOH I find that it is out of scope for gnulib, because
gnulib's target API is POSIX and glibc, not Solaris and not FreeBSD.
