Is it possible to build master or gcc-7 branch of GDC from source against GCC?

If so, which of the instructions

- https://wiki.dlang.org/GDC
- https://wiki.dlang.org/GDC/Installation/Generic

should I follow?

Even better, have anybody already got a script that does this?

Moreover, commit

https://github.com/D-Programming-GDC/GDC/commit/2141559f78912b75ef7f9edc6e2d5548ea5ae282

has message "the frontend sources are now at 2.076". Does this mean that master compiles a working D compiler compatible with DMD 2.076?!!!

Pretty much. Our CI script can be used as a reference too.

C++ headers are aligned with 2.076, as well as all regressions in the changelog backported.  We can build phobos 2.076 and pass all unittests. Not all features have been backported from D however. Notably static foreach in the upcoming release (and I have no plans to port it).

Moving to self hosted (ddmd) is something that will happen soon.

Does this mean that gdc will never have static foreach?

No, it just means that maintained fork of the C++ implementation will not support static foreach.

The D implementation when its finally branched + working with bootstrapped builds (non-bootstrapped builds are fine and pass all tests) will initially use 2.076 proper, and so will come with all features, including static foreach.
