I'll see about add= ing this feature test macro to FreeBSD to specify you also want isoc11 features. That would be compatible with glibc and other systems, as well as being something to fill in the gap before the open group updates posix to align i= t to a newer version of C. This would also preserve purely standards conforming programs that just hap= pen to be compiled with a c11 because the system default has changed, and be minimally intrusive a change for code ported from other systems. --=20 You are receiving this mail because: You are the assignee for the bug.=
