Bug#947235: port patches to gcc-10

[Dima Kogan]

I just uploaded cross-gcc-dev=241. A patch stack for gcc-10 is included.
The patches apply (they come from a git tree, as all the other patch
stacks). I have not actually attempted to build a compiler using these
patches, and clearly I have not tested the output from such compiler.
Please let me know if something doesn't work.

Bug#947235: port patches to gcc-10

[Helmut Grohne]

Package: cross-gcc-dev
Severity: important
User: helm...@debian.org
Usertags: rebootstrap

Please add an initial patch stack for gcc-10 from experimental. If it
doesn't work, I'll send patches to make it work. Just make it available
soon please. If you also check that the patches apply, that could save a
few round trips. Thank you.

Helmut
