Then maybe add the testcase and close both issues?

Untested fix. It makes no sense to instrument clobbers, so that is what the
patch does.

I've looked into c++config.h and I'm sure mingw-w64 4.9.1 distro of msys2 uses
clock_gettime defined in winpthreads:
/* Defined if clock_gettime syscall has monotonic and realtime clock support.
*/
/* #undef _GLIBCXX_USE_CLOCK_GETTIME_SYSCALL */
/* Defined if clock_gettime has monotonic clock support. */
#define _GLIBCXX_USE_CLOCK_MONOTONIC 1
/* Defined if clock_gettime has realtime clock support. */
#define _GLIBCXX_USE_CLOCK_REALTIME 1
/* Defined if gettimeofday is available. */
#define _GLIBCXX_USE_GETTIMEOFDAY 1
Here is the output (g++ -std=c++11):
a.cc:7:2: warning: #warning system_clock using clock_gettime(CLOCK_REALTIME,
&tp); [-Wcpp]
#warning system_clock using clock_gettime(CLOCK_REALTIME, &tp);
^
a.cc:19:2: warning: #warning steady_clock using clock_gettime(CLOCK_MONOTONIC,
&tp); [-Wcpp]
#warning steady_clock using clock_gettime(CLOCK_MONOTONIC, &tp);
