The NetBSD operating system 7.0 has been formally announced today (and
antedated to 26 Sep)!

http://www.netbsd.org/releases/formal-7/NetBSD-7.0.html

I acquired a fresh NetBSD-7.0 machine (amd64 port), the current
parameters allow to build LLVM+Clang+LLDB (all platform backends) with
CMake & ninja within <40 minutes.

pkgsrc packages:
cmake-3.3.1
ninja-build-1.6.0
swig-1.3.38nb1
python27-2.7.10
ncurses{,w}-6.0nb1

Host toolchain:
$ ld -v
GNU ld (NetBSD Binutils nb1) 2.23.2
$ gcc -v
Using built-in specs.

I'm waiting for credentials for my buildbot-slave from Galina Kistanova.

I've verified that NetBSD-7.0 builds properly lldb with my patches for
NetBSD. Please help me to make merged the current code from review.

http://reviews.llvm.org/D13334 Preliminary NetBSD support
http://reviews.llvm.org/D12995 Add support for lldb config.h and
detect ncurses' include path
http://reviews.llvm.org/D12994 Improve support of the ncurses
dependency on NetBSD

When this will make happen I will send remaining glue to make it
buildable.

I develop locally on NetBSD-current/amd64, buildbot works on 7.0,
which is the minimal version I plan to support.

Thank you for your cooperation!
