Hello GHC devs, A few minutes ago, I landed `integer-gmp2` to master! Ideally, you shouldn't notice any breakages (I've tried to make sure all tier-1 platform configuration work...), but if you do have problems, please report any issues/regressions you encounter to me! Morever, should something break in a way that blocks you on your platform, just add "INTEGER_LIBRARY=integer-gmp" to the end of your mk/build.mk (or edit mk/config.mk.in locally), and you'll get the "old" integer-gmp which worked previously, so you can continue hacking on GHC HEAD while I figure out what's broken for you with `integer-gmp2` (assuming you reported the issue to me...).
