Are there also 8 bit systems where Lua compiles
(maybe on some micro controllers)?

O.K., seems that LUA_VERSION_NUM already has the right value
(501 for 5.01), and the current macro system doesn't allow to
distinct between bug fix releases.

Thus the post is a suggestion for a additional feature.

Maybe it is worth to think about the macro names when adding
a bug fix version macro, e.g.:

LUA_VERSION_NUM            and  LUA_VERSION_BUGFIX__NUM or
LUA_MAJOR_VERSION_NUM      and  LUA_MINOR_VERSION_NUM   or
LUA_LUANGUAGE_VERSION_NUM  and  LUA_IMPL_VERSION__NUM   or
....
