Hi
Second question: is there a preferred way to rebuild Prelude.hi? I've been using yhc -c -rebuild -prelude Prelude.hs and copying the result into bootstrap/.
Does this work reliably? Does it have a dependancy on the initial Prelude.hi file thats already there?
No. I encountered exactly the instance Integral problem that Dimitry just reported. I spent some time searching for the problem and couldn't figure it out. I could make a lot of half-informed observations on this issue. I'll restrict myself to this one: It seems like a design flaw that Prelude.hs is mutually dependent on several other modules. My work so far has led me to suspect that mutually dependent modules are never necessary. (And always annoying.) -- Lane
