Re: [PATCH, boehm-gc, AArch64] Add AArch64 support

[Marcus Shawcroft <marcus.shawcroft@gmail.com>]

Hi Yvan,  My understanding of the 'Free for all' section of
http://gcc.gnu.org/svnwrite.html#policies is that since this is a
backport from an upstream project you do not need to seek further
approval to commit this change.

Cheers
/Marcus
