Hi!
Pls. excuse me for cross-posting - I did not realize that this list is more
appropriate for the problem for which I posted a message on users' list.
After having problem in building ghc-6.2 from source tarball, I installed
ghc-6-2-1.msi build and then tried to compile darcs with it, but,

Ferenc, thanks for your answer. It doesn't really solve my problem though...
1. Your method doesn't preserve the line-breaks within the resulting string.
2. Surrounding each line with special chars is actually what I want to
When -fwarn-unused-imports is switched on, import M() should not issue
a warning. In 6.2, it does.
The idea is that I only wish to import instance declarations here, and
that's the obvious way of making that explicit. I'm using -Werror (new
in 6.2, thanks), and most of the time I'm interested
I'm pretty new with GHC and I have prblem building ghc 6.2 with MinGW compiler
in MSYS environment.
After running configure --prefix=/mingw ; make
make fails with:

enough, configure script fails when trying to compile Hello world! program.
I tried to compile:

It occurs to me that Haskell would be quite a bit easier for OO and
traditional programmers to grasp if Haskell would actually use the
correct, or at least more commonly used, names for things.
For instance,

Hi,
prelude :t map (foldr filter)
map (foldr filter) :: [[a]] - [[a - Bool] - [a]]
Two main questions:
1/ How does hugs derive this answer?
2/ What input can I give so that it yields a correct result? I've tried
giving it a list of lists but it fails...
Try:
map (flip (foldr filter)
