| Subject: Build failure with HEAD
| 
| Hi,
| 
| Building GHC HEAD (git HEAD SHA1 =
| 88f476b98709731d997ab57612cce4753cb65a0a) this morning, I've encountered 2
| build failures that seem to be a result of some recent changes in the past
| day or two.
| 
| If I build a clean repository with `make -j13` on my 12 core machine, I get:
| 
| -----------------------------------------------------------------------------
| -
| compiler/hsSyn/Convert.lhs:178:30:
|     `td_fvs' is not a (visible) field of constructor `TyData'
| 
| compiler/hsSyn/Convert.lhs:190:31:
|     `td_fvs' is not a (visible) field of constructor `TyData'
| make[1]: *** [compiler/stage2/build/Convert.o] Error 1
| make[1]: *** Waiting for unfinished jobs....
| ---------------------------------------------------------------------------
| 
| However, reinvoking `make` with no parallelism and attempting to continue the
| build (there's no race condition obviously, I was just
| curious,) I get another (possibly related) build failure as well:
| 
| ---------------------------------------------------------------------------
| compiler/deSugar/DsMeta.hs:326:18:
|     Constructor `FamInstD' should have 2 arguments, but has been given 1
|     In the pattern: FamInstD fi_decl
|     In the pattern: L loc (FamInstD fi_decl)
|     In an equation for `repInstD':
|         repInstD (L loc (FamInstD fi_decl))
|           = do { dec <- repFamInstD fi_decl;
|                  return (loc, dec) }
| make[1]: *** [compiler/stage2/build/DsMeta.o] Error 1
| ---------------------------------------------------------------------------
| 
| I would assume someone forgot to push something perhaps, but I figured
| naturally someone should be aware so they can fix it. :)
