R-4.6.1/src/include/R_ext/Error.h

[Makoto mef Fujiwara <makoto%if.t.u-tokyo.ac.jp@localhost>]

The commit (of myself)
  https://mail-index.netbsd.org/pkgsrc-changes/2025/03/02/msg318732.html
may not be correct, or
  math/R/patches/patch-src_include_R__ext_Error.h
is not correct for now,

    43        (defined(__cplusplus) && __cplusplus >= 201103L)

    51  #else
    52  // C++ and legacy
    53  # define NORET
    54  #endif

The line 45 among above:

    45  # define NORET [[noreturn]]
is takeen by 21.6.0 Darwin, clang
    Apple clang version 14.0.0 (clang-1400.0.29.202)
(I'm not so sure for this)

But This Darwin case the definition should be
    # define NORET __attribute__((noreturn))

Because of this, (at least)
    devel/R-Rcpp  (1.1.1.1)
could not be packaged on Darwin for the moment

I'll take a look more, but if anybody who knows better, please
fix this issue, thanks,

I'm afraid gcc-7.5.0 (on NetBSD/amd 9.4) suffers from this also,
but it is warning level for now, and packaging can be done ;-(
