Added missing include of <stdexcept>.

Also there are several versions of the runtime_error constructor:

std::runtime_error( const std::string& what_arg ); // C++03
std::runtime_error( const char* what_arg );  // since C++11

The error message argument of the std::runtime_error is copied to an internal member of the runtime_error, so the initial object does not have to remain valid after an exception is thrown.

If C++03 is used, an implicit conversion from const char* to std::string should happen.

To Consider

• m_strIndexErr could be defined in srterror_defs.cpp.
