Hello,
I'm trying to compile HEAD on amd64-solaris2 platform, but the build
fails with:

Perhaps you meant ‘TyFamInstD’ (imported from GHC)
utils/haddock/src/Haddock/GhcUtils.hs:105:36:
‘tfie_rhs’ is not a (visible) constructor field name
gmake[1]: *** [utils/haddock/dist/build/Haddock/GhcUtils.dyn_o] Error 1
gmake: *** [all] Error 2
is this just issue on my system or general issue which waits for someone
to resolve it?
Since I built HEAD successfully just two days ago, this patch may looks
suspiciously:
commit 9b8ba62991ae22420a0c4486127a3b22ee7f22bd

Entirely re-jig the handling of default type-family instances
(fixes Trac #9063)
In looking at Trac #9063 I decided to re-design the default
instances for associated type synonyms. Previously it was all
jolly complicated, to support generality that no one wanted, and
was arguably undesirable.
Specifically
* The default instance for an associated type can have only
type variables on the LHS. (Not type patterns.)
* There can be at most one default instances declaration for
each associated type.
To achieve this I had to do a surprisingly large amount of refactoring
of HsSyn, specifically to parameterise HsDecls.TyFamEqn over the type
of the LHS patterns.
That change in HsDecls has a (trivial) knock-on effect in Haddock, so
this commit does a submodule update too.
The net result is good though. The code is simpler; the language
specification is simpler. Happy days.
Trac #9263 and #9264 are thereby fixed as well.
but I'm not expert so no offense! And if this is a mistake on my side,
then I'm really sorry for false alarm.
Thanks!
Karel
