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. [...]
