Ah. I was about to checkin a replacement for System.Posix.Types (in base) that uses hsc2hs instead of autoconf.

Anyway, to answer your question, using hsc2hs in System.Posix.Types will cause problems for bootstrapping GHC, yes, because we can't run hsc2hs on the target without GHC, but we can run configure.

But it is only a problem for cross-compiling - yes?

Yes.

And no more of a problem than ghc already has?

No, with the configure method we can run configure on the target and copy the files back to the host. The instructions at http://hackage.haskell.org/trac/ghc/wiki/Building/Porting do so for includes/ghcautoconf.h includes/DerivedConstants.h includes/GHCConstants.h and look like they ought to for libraries/base/include/HsBaseConfig.h too. But we can't run hsc2hs on the target without having a Haskell compiler there. Thanks Ian
