A proprietary compiler that we're using is generating a warning on
TestReporterStdout::ReportSummary, because the header declaration does not exactly match the
source definition.

TestReporterStdout.h:

virtual void ReportSummary(
  int totalTestCount, int failedTestCount, int failureCount, float secondsElapsed);

TestReporterStdout.cpp:

void TestReporterStdout::ReportSummary(
  int const totalTestCount, int const failedTestCount, int const failureCount, float secondsElapsed)

Notice the extra "const"s in the definition. Even though they're arguably compatible, it's a bit of a
gray area. Even MSVC will complain in some cases when function signatures differ by a const
qualifier.

The simple fix is just to remove the consts in this cpp file.
