  commit c85e54ac6cef0faed7b7ffc722f52523dec59bf5
  Author: Gabriel F. T. Gomes <gabriel@inconstante.eti.br>
  Date:   Fri Nov 3 10:44:36 2017 -0200

      Provide a C++ version of iseqsig (bug 22377)

mistakenly used double parameters in the long double version of iseqsig,
thus causing spurious conversions to double, as reported on bug 23171.

Tested for powerpc64le and x86_64.

(cherry picked from commit fb0e10b8eb1ebb68c57d4551f7a95118f3c54837)
