Comment (by simonpj):
Fixed by
{{{
Thu May 28 17:49:00 BST 2009 simo...@microsoft.com
* Fix Trac #3261: make default types play nice with -Werror
The trial-and-error for type defaults was not playing nicely with
-Werror. The fix is simple.
M ./compiler/typecheck/TcSimplify.lhs -6 +7
}}}
That now shows up a warning as an error, so you need this too:
{{{
Thu May 28 17:45:25 BST 2009 simo...@microsoft.com
* Remove type-ambiguous (fromIntegral 0)::Int, replacing it with just 0
This unnecessary ambiguity has been there for ages, and is now rejected
by -Werror, after fixing #3261
M ./compiler/ghci/ByteCodeAsm.lhs -1 +1
}}}
And there's a similar case in `Float.lhs`, still to fix.
Simon

With `q.hs`:
{{{
module Foo where
foo :: Int
foo = ceiling 6.3
}}}
I get:
{{{
$ ghc -fforce-recomp -c q.hs -Wall
q.hs:5:6:
