Subject: Remove -XImpredicativeTypes from -fglasgow-exts
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=d8c657765fd403be4604e4f902eaa4e0f54f4afc

Remove -XImpredicativeTypes from -fglasgow-exts

See Trac #2846: impredicative types are far from stable, so
-fglasgow-exts should not imply them.  Maybe we should merge
this into 6.10?
