The message formatting was a lot better.  But:

builtin-gc.c:65: warning: passing argument 1 of 'git_config_string' from incompatible pointer type

>From http://git.or.cz/gitwiki/Janitor:

  This is because the first argument to "git_config_string" should
  be a "const char **", not a "char **". There will be a compile
  time warning if a "char **" is passed instead of a "const char **"
  and the patch will be rejected. (And no, casting the "char **"
  into a "const char **" is not a good solution either.)"
