  Issue 21941 - Extend the list of reserved words for dtoh

  Adds several entries regarding C(++) keywords, extensions and default
  macros provided by gcc and clang. Also rejects all identifiers starting
  with __ because those are reserved by C++ compilers

  Doesn't "fix" the issue because the list is confined to common keywords
  and not an exhaustive list of all possible extensions.
