bootstrap openbsd powerpc - continues

[Jake L]

Okay, I worked through the .h issue(it was late at night), but wasn't 
able to make headway with 6.6.1(exception type ambiguities), so I switched 
platforms and downgraded to earlier versions:

take 2
------
target = powerpc-unknown-openbsd
host   = i386-unknown-linux with a running ghc 6.4.2

following the instruction here:
http://www.haskell.org/ghc/docs/6.4.2/html/building/sec-porting-ghc.html#id2931737

it finished the compiler phase's make boot && make (it didn't build RTS as 
the instruction fortold)

however, it now fails in the phase
$ cd H/libraries
$ make boot && make


------------------------------------------------------------------------
==fptools== make boot -r;
  in /j/ghc-6.4.2/libraries/unix
------------------------------------------------------------------------

some digging appears what I have ran into this bug:
http://hackage.haskell.org/trac/ghc/ticket/729

any suggestions?
