* internal.h (WARN_UNUSED_RESULT): moved to configure.in, to
actually check its availability rather to check GCC's version. * configure.in (WARN_UNUSED_RESULT): moved to here. * configure.in (RUBY_FUNC_ATTRIBUTE): change function declaration to return int rather than void, because it makes no sense for a warn_unused_result attributed function to return void. Funny thing however is that it also makes no sense for noreturn attributed function to return int. So there is a fundamental conflict between them. While I tested this, I confirmed both GCC 6 and Clang 3.8 prefers int over void to correctly detect necessary attributes under this setup. Maybe subject to change in future. * internal.h (UNINITIALIZED_VAR): renamed to MAYBE_UNUSED, then moved to configure.in for the same reason we move WARN_UNUSED_RESULT. * configure.in (MAYBE_UNUSED): moved to here. * internal.h (__has_attribute): deleted, because it has no use now. * string.c (rb_str_enumerate_lines): refactor macro rename. * string.c (rb_str_enumerate_bytes): ditto. * string.c (rb_str_enumerate_chars): ditto. * string.c (rb_str_enumerate_codepoints): ditto. * thread.c (do_select): ditto. * vm_backtrace.c (rb_debug_inspector_open): ditto. * vsnprintf.c (BSD_vfprintf): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56169 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
