[GiNaC-list] Various syntax errors while compiling appln. with Ginac1.7.1

[Thomas Luthe]

Hi Harish,

GiNaC started using C++11 features in a recent version, which is where
the noexcept keyword was introduced to C++. Adding -std=c++11 to your
compile options should fix the problem if your compiler version supports
C++11.

Cheers,
Thomas
