Bug in GHC HEAD on Windows?

[Felix Martini]

I've pulled and compiled GHC HEAD on Windows (with build setting
'fastest'). When i start ghci i get the error message

C:\ghc\ghc-head\bin>ghci
GHCi, version 6.9.20080416: http://www.haskell.org/ghc/  :? for help
: Unknown PEi386 section name `.reloc' (while processing:
C:\ghc\ghc-head\ghc-prim-0.1\HSghc-prim-0.1.o)
Loading package ghc-prim ... : panic! (the 'impossible' happened)
 (GHC version 6.9.20080416 for i386-unknown-mingw32):
       loadObj: failed

Is this a known issue?

Felix
