  12 //  Dynamic link libraries (DLL's), also know as dynamic shared objects (DSO's),
  13 //  can cause symbol visability problems unless carefully configured. One of the
  14 //  manifestations, particularly with GCC, is that a system_error exception thrown from
  15 //  a DLL or DSO is not caught.
  16 //
  17 //  The purpose of this program is to test for that error.
