bind-9.12.2-P2 fails to compile with baffling undefined symbol issues

[Dennis Clarke]

This has me baffled :

There is no such thing as TG_atomic anywhere in any sources and there is 
a small reference to it in the config.log :

"conftest.c", line 105: warning: implicit function declaration: 
_TG_atomic_fetch_add
"conftest.c", line 101: warning: implicit function declaration: 
_TG_atomic_fetch_add
_TG_atomic_fetch_add                conftest.o


Something obvious here ??
