Has anyone else ran into this problem. Am I making a mistake?

In the terminology of the build system, you're building with host=i386-unknown-mingw32 and target=i386-unknown-cygwin32. Try configuring with those options.

Sounds like the compiler's Makefile should be checking the host rather than the target when adding -package unix too.

(Again, I am building from 6.2.1).

If I try to configure cygwin with host = "i386-unknown-mingw32", target = "i386-unknown-cygwin32" it complains that cross compilation is not supported. Did you mean I should go through the cross compilation process?

Well it *is* a cross-compilation, of a kind. It is true that the build system isn't really set up to handle cross-compilation. I'm afraid this is going to be a bit of a non-answer. Building for cygwin is something that isn't officially supported, and it almost certainly requires tweaking the build system and Makefiles to get it to go through. I can't tell you how much, because I've never done it.

Is there an unofficial binary release for ghc-6.2.1 on cygwin?

Not that I know of.

All I really need is Readline which is not built into the mingw binary release. Initially I tried to get the mingw build to work. This failed. The script 'configure' hangs in the step "checking if your perl works in shell scripts".

Has anyone had this problem?

Nope, never seen this one. Perhaps try a different Perl? The one shipped with GHC seems to work well. It looks like MingW comes with a libreadline.a these days. Readline appears to build fine in GHC 6.2.2. I'll see if we can include it with the 6.2.2 release... Cheers, Simon
