How do we deal with portability issues in nhc? The code I submitted will
run find on the BSDs and Linux, but for Solaris, Irix, HPUS, and Darwin
when need slight variations (which ghc currently has) (and we're stuck
with malloc on Windows).

Does nhc have some equivalent of the 
    #if defined(solaris2_HOST_OS) || defined(irix_HOST_OS)
macros?
