Failure building HEAD in libraries/base/Data/ByteString.hs

8 May 2006

      I get the following error when trying to bootstrap the 6.5.20060506  
snapshot from hc files (registerised):

I am insufficiently experienced with the build process to know if  
this was from an error in creating the .hc file or a problem with the  
source.  I have noticed that the file ByteString.hs seems to be new.

I am building the .hc files on 386 linux (Ubuntu breezy badger):
	linux kernel  2.6.12
	ghc-6.5.20060502 is installed
	gcc is 4.0.2

I am using the registerised .hc files to bootstrap to Max OS X x86
	Mac OS X 10.4.6
	no ghc installed
	gcc is 4.0.1 (as included in Xcode)
