In this patch commit 6eabb6dd Author: Simon Peyton Jones <simonpj@microsoft.com> Date: Tue Dec 15 14:26:13 2015 +0000 Allow recursive (undecidable) superclasses I changed (transSuperClasses p) to return only the superclasses of p, but not p itself. (Previously it always returned p as well.) The use of transSuperClasses in TcErrors.warnRedundantConstraints really needs 'p' in the result -- but I faild to fix this call site, and instead crippled the test for Trac #10100. This patch sets things right * Accomodates the API change * Re-enables T10100 * And thereby fixes Trac #11474 (cherry picked from commit 4293a80a)
