Comment(by dterei):

 I know this is closed but just thought I would add the results these days:

 {{{
 ghc -O2 -optlo-O3 -fllvm Hash c_hash.c
 }}}

 {{{
 Hash h  10: 0.29s | Hash c  10: 0.38s
 Hash h  50: 0.97s | Hash c  50: 1.02s
 Hash h 100: 1.94s | Hash h 100: 2.04s
 }}}

 I guess we could change this to fixed now instead of wontfix :).
