Re: devel/arm-none-eabi-newlib headers inconsistencies (not functional) or am I misusing something?

Linking is another chapter that will be written after we can obtain 
objects.

For the time being I am buinding a number of tests to see if the headers 
are functional or not, following your suggestion to add newlib ports 
header path first, and then arm-noabi-gcc header paths. I.e.
#include <...> search starts here:
  /usr/local/arm-none-eabi/include
  /usr/local/lib/gcc/arm-none-eabi/11.3.0/include
  /usr/local/lib/gcc/arm-none-eabi/11.3.0/include-fixed
End of search list.

In this scenario the next problem I am hitting is this one:
% arm-none-eabi-gcc test_stdatomic.c -c -g -DDEBUG -pipe -nostdinc 
-isystem /usr/local/arm-none-eabi/include -isystem 
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include -isystem 
/usr/local/lib/gcc/arm-none-eabi/11.3.0/include-fixed -o 
test_stdatomic.o

% cat test_stdatomic.c
#include <stdint.h>
#include <stdatomic.h>

int main(int argc, char *argv[]) {
   return 0;
}

Any suggestion before I patch 
/usr/local/arm-none-eabi/include/stdatomic.h to make it work?

Thank you.

BR,
