  42    and help with comparison with the original tests, the file names
  43    have been preserved, and only minimal modification was done to have
  44    them compile against gdb::optional instead of std::optional:
  45
  46      - std::optional->gdb:optional, etc.
  47      - ATTRIBUTE_UNUSED in a few places
  48      - wrap each file in a namespace so they can all be compiled as a
  49        single unit.
  50      - libstdc++'s license and formatting style was preserved.
