3.0 is a good timing for that "future".
According to MSVC manual (*1), cl.exe can skip including a header file
when that:
- contains #pragma once, or
- starts with #ifndef, or
- starts with #if ! defined.
GCC has a similar trick (*2), but it acts more stricter (e. g. there
must be _no tokens_ outside of #ifndef...#endif).
Sun C lacked #pragma once for a looong time. Oracle Developer Studio
12.5 finally implemented it, but we cannot assume such recent version.
This changeset modifies header files so that each of them include
strictly one #ifndef...#endif. I believe this is the most portable way
to trigger compiler optimizations. [Bug #16770]

* include/ruby/backward.h (rb_frame_method_id_and_class): we had labeled
`rb_frame_method_id_and_class()` as deprecated because MRI internal
doesn't use it, but we found there are user of this API in external
C-extensions. Now we don't have proper alternative API and no time
to make alternative API, so I remove "deprecated" label.

removed useless declarations which have been deprecated from the

Just refactoring. Despite its name, the function does NOT return a
boolean but raises an exception when the class given is frozen.
I don't think the new name "rb_class_modify_check" is the best, but
it follows the precedeint "rb_ary_modify_check", and is definitely
better than "*_p".

because it was actually used in
https://github.com/tmm1/rbtrace/blob/v0.4.8/ext/rbtrace.c#L329
and deprecated in r60579 AFTER removal in r60558.
ko1 agreed that we should keep just deprecated in Ruby 2.5 and remove it
later, and I'm commiting this because I want to make rbtrace.gem
installation successful.
backward.h: modify r60579 to make rb_frame_method_id_and_class()
compilable.

fallback to rb_cInteger.

macro.
