Hello Alexey, this file was imported from FreeBSD. So, it would be good to fix this issue first in FreeBSD. If GCC provides the c_atomic and cxx_atomic extensions, then why can't we use them for this header file? Independent of this, GCC provides its own stdatomic.h header file for a while which should be found before the Newlib header if you use standard compiler search paths. ----- Am 8.
