   and help with comparison with the original tests, the file names
   have been preserved, and only minimal modification was done to have
   them compile against gdb::optional instead of std::optional:

     - std::optional->gdb:optional, etc.
     - ATTRIBUTE_UNUSED in a few places
     - wrap each file in a namespace so they can all be compiled as a
       single unit.
     - libstdc++'s license and formatting style was preserved.
