Mingw-packages: GCC v7.1

[Barough]

GCC v7.1 have been released now and im wondering if it's being looked into and will be added.

https://gcc.gnu.org/ml/gcc/2017-05/msg00017.html

[stephenwhittle]

I successfully built it using the PKGBUILD script here in this repository: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-gcc-git

Im assuming this means we'll see a binary package being made available shortly.

[Alexpux]

I don't want to build GCC 7 soon as need first to see if we have ABI compatibility issues. If issues present then we need rebuild nearly all C++ package with GCC7. I don't have time to do it now

[bit2shift]

It's not building for me because of #2463. And I really need to build it, because C++17.
Any tips?

It really doesnt work using the PKGBUILD script? As mentioned earlier in the thread, about 10 days ago I got it to build using that script and makepkg-mingw.

Patches for the __in and __out issue:

1. This for gcc-5-branch.
2. This for gcc-6-branch.
3. And this for gcc-7-branch.

[bit2shift]

I applied the patch from #2464 and it seems to be working now.
Via sed in PKGBUILD.

[bit2shift]

2139 also applies to mingw-w64-gcc-git

Any news/info regarding the new GCC 7.x

@ArekPiekarz Thnx for the info. Seems like it's getting closer :)
