--- Comment #37 from bkorb at gnu dot org 2012-01-09 22:11:09 UTC ---
It is getting too confusing.
+/*
+ * 'g++ -std=c++11' defines __cplusplus to 201103L, which suggests
+ * that it conforms to ISO/IEC 14882:2011. Until G++ fully conforms,
+ * it should not set __cplusplus to that value. It currently does
+ * not support the [[noreturn]] procedure attribute.
+ * When it does, this hack should be removed.
+ * SEE: gcc.gnu.org/bugzilla/show_bug.cgi?id=51776
+ */
+fix = {
+ hackname = cdef_cplusplus;
+ files = sys/cdefs.h;
+ select = '\[\[noreturn\]\]';
+ c_fix = format;
+ c_fix_arg = '__attribute__((__noreturn__))';
+ test_text = "#define _Noreturn [[noreturn]]";
+};
This is the fix/hack that should be used.
There will also be a change required for tests/base/sys/cdefs.h.
The following is also correct, since I read a more recent GNU Coding
standards that makes it clear to not use "Ver." in the version.
This is approved. Regards, Bruce
