Don't use SIGC_USING_STD()

Kjell Ahlstedt · Kjell Ahlstedt · commit 260d2fd74c39 · 2015-12-17T15:17:12.000+01:00
The SIGC_USING_STD() macro is defined as an empty string, if some standard
C++ symbols are defined in namespace std. They always are.
Since many years, SIGC_USING_STD() is an unnecessary macro.
