[Bug 1748945] Re: Please backport gcc-mingw-w64 20.2 (universe) from bionic-proposed

[michagogo]

I tried to push this up to my PPA, but ran into dependency issues... It
wants the following: binutils-mingw-w64-i686 (>= 2.28~), binutils-
mingw-w64-x86-64 (>= 2.28~), g++-7, gcc-7-source (>= 7.2.0-20), gnat-7

I tried backporting binutils-mingw-w64 to the PPA, that then wanted
binutils-source, which comes from src:binutils. When I tried binutils, I
got a weird error:

# Pastebin dFgEDKXz

And when I tried g++-7, all kinds of other stuff started popping up,
causing me to suspect that I'm going down a rabbit hole I shouldn't be.
Is there something else I should be doing?

Thanks!
