What I know is that Linux by default uses c_global. There is configury

selecting the directory, but I didn't write the logic, Benjamin did, frankly I

don't know which specific target use c_std these times. In such case the safe

thing to do in my opinion is changing in a consistent way existing bits in the

headers and not adding or removing anything else.
