Comment (by rhaas):

 I agree with Ian in not liking Cactus re-defining reserved words of the
 language ("inline", "restrict") and possibly double (or single which are
 reserved for the C standard library for that matter) underscored symbols.
 I am not sure I buy into the "looks ugly" argument. If the issue is only
 syntax highlighting, then it is usually simple to extent one's favorite
 editor's syntax files to cope with CCTK_XXX items (and eg CCTK_REAL,
 CCTK_INT etc as well). My thoughts about M_PI which is a macro to begin
 with are less strong, there I don't mind if Cactus provides a definition
 of the environment does not (as long as it is the correct value of pi).

 So I'd be happy having all of these things be CCTK_STATIC_INLINE
 CCTK_RESTRICT etc again. Of course this means that we are re-inventing the
 wheel as far as names goes.
