  * Use libcharset instead of nl_langinfo(CODESET) if possible.
  
  nl_langinfo(CODESET) doesn't always return standardized variations of the encoding names. Use libcharset if possible, which is shipped together with GNU libiconv.

    M ./GHC/IO/Encoding/Iconv.hs -6 +3
    M ./cbits/PrelIOUtils.c -5 +19
    M ./configure.ac +11
