include/ruby/subst.h: skip doxygen

2021-09-10T11:00:06+00:00

Nothing worth documenting in this file. [ci skip]

add #include guard hack

2020-04-13T07:06:00+00:00

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]

  (vsnprintf): ditto.

* include/ruby/subst.h: new file for substitute standard functions..

2010-08-07T15:44:27+00:00

* include/ruby/missing.h: don't substitute "close", etc. here.

* include/ruby/ruby.h: include ruby/subst.h at last.
  This prevents substituting "close" in unitstd.h.
