It's a warning from the byte compiler that it found `?(' and `?)' in
elisp code, which should be written as `?\(' and `?\)'.  See (info
"(elisp) Basic Char Syntax"):

  The usual read syntax for alphanumeric characters is a question mark
  followed by the character; thus, ‘?A’ for the character ‘A’, ‘?B’ for
  the character ‘B’, and ‘?a’ for the character ‘a’.
  [...]
     You can use the same syntax for punctuation characters.  However, if
  the punctuation character has a special syntactic meaning in Lisp, you
  must quote it with a ‘\’.  For example, ‘?\(’ is the way to write the
  open-paren character. [...]
