Dear Maintainer,

GCC 11 defaults to C++17 which does not allow dynamic exception specifications
anymore: https://gcc.gnu.org/gcc-11/porting_to.html

In Ubuntu, the attached patch was applied to replace the throw(...)
specifications in the recommended way:

  * Fix FTBFS with GCC-11 by avoiding dynamic exception specifications


Thanks for considering the patch.

Cheers,
  Lukas
