Yes, these were internal details of the Hugs implementation of the
Prelude, and shouldn't have been exposed.  They were only ever visible
when the Prelude was the current module, and have been properly hidden
since the November 2002 release.

But since they existed only to implement Haskell 98, there are always
Haskell 98 alternatives, e.g. minBound::Int for primMinInt, as already
