_Noreturn is safe but I am more affraind by the fact that cpp run in
traditionnal mode and could choke if snippet include C89/C99
preprocessor directive.

Yes this could work, but I will prefer something that will avoid snippet if
other language than c,c++ (objc?)
I merely use config.h for project that include c/fortran/c++/python mix and
even verilog ...
My config.h will consist of only #define something 1 guarded by #if #endif that
is safe is all the previous language.
Antoher problem, but not surelly related I use AX_PREFIX_CONFIG_H and I get
__UNUSED_PARAMETER prefixed...
Thanks
