--- Comment #1 from David Majnemer <david.majnemer at gmail.com> ---
C11 

C++11 2.14.3 [lex.ccon]/p3:
  Escape sequences in which the character following the backslash is not listed
in Table 7 are conditionally-supported, with implementation-defined semantics.

Table 7 does not include the right parenthesis character and thus clang chooses
to warn because it cannot recognize it as an escape sequence.

Note that GCC and EDG both issue a very similar diagnostic.
