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

[Reilly Hayes]

Gentlemen,

ghc -v was not required, as I am building this using .hc files from  
another host.  Adding "-fno-builtin" to the CC opts did resolve the  
problem.  Furthermore, I believe I have confirmed that strlen is the  
problem by succesfully compiling the library using "-fno-builtin- 
strlen" instead of "-fno-builtin".

Thank you,

reilly hayes
