A few tools within nhc98 are built by the bootstrapping compiler:
hmake, greencard, nhc98 itself, cpphs, and hsc2hs
My question is: What should be the minimum requirement for the bootstrapping compiler? Haskell 1.4? Haskell 98? The latter would be preferable IMHO, because we have quite a few Haskell-98-conformant systems nowadays :-) and the code could be cleaned up a bit.
I think that we ought to be able to assume Haskell'98 by now, but unfortunately that excludes hbc and Helium, leaving only ghc, Hugs, and nhc98 itself. However, the nightly hbc builds have been broken for a long time anyway, and I haven't had any motivation to fix them, so I wouldn't object to removing any older, 1.4-related stuff. Since nhc98 is self-bootstrapping via C, I can't see any good reason to continue to support older versions of ghc either. Regards, Malcolm
