Comment (by snowleopard):

 Alp, thanks for tagging me!

 As far as I understand, `iserv` is not supported on Windows, so when
 running the testsuite on Windows, we shouldn't depend on it and skip all
 associated tests.

 I guess, this line may be relevant:

 https://gitlab.haskell.org/ghc/ghc/blob/aad05fb3b36b93b919622f8a6dc032109d040d16/hadrian/src/Settings/Default.hs#L137

 Andreas: perhaps, you could try making `iserv` conditional, as for
 example, here:

 https://gitlab.haskell.org/ghc/ghc/blob/aad05fb3b36b93b919622f8a6dc032109d040d16/hadrian/src/Settings/Default.hs#L115

 Does this help?
