+ =?utf8?q?=E2=89=A5=207.8?=
+MIME-Version: 1.0

+GHC 7.8 renamed "Gcc Linker flags" to "C compiler link flags" and "Ld
+Linker flags" to "ld flags"
+(https://ghc.haskell.org/trac/ghc/ticket/4862).
+
+Without this corresponding fix in Cabal, the old-time package fails to
+compile on Ubuntu yakkety amd64, where the system GCC now defaults to
+-pie and GHC has
+
+    $ ghc --info | grep -i pie
+     ,("C compiler flags","-fno-PIE -fno-stack-protector")
+     ,("C compiler link flags","-no-pie")
+     ,("ld flags","-no-pie")
