--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Implementation of Levenshtein distance (in C++) committed to trunk as r230285;
currently we offer hints for misspelled command-line options (PR 67613), and in
the C FE for misspelled fields.

There's plenty more that could be implemented; see:
  https://gcc.gnu.org/ml/gcc-patches/2015-09/msg01090.html
for some other implementation ideas.
