[Haskell-cafe] Announce: Haskell Platform 8.6.5 (Gershom B)

package from msys2.)

Windows uses a statistically linked gmp built from source during the ghc
bootstrap. It does not use libgmp from msys2.
The difficulty here is that Haskell programs should work regardless of if
you're running in msys2 or not. Compared to other languages that are
dynamically linked ghc has no "runtime libraries". You'd have to ship
libgmp with every application you make.
