newlib license question

[An, Douwa]

Dear,


I am struggling with the newlib license since i saw GPL license in git repo.


It declares that newlib subdirectory is non-GPL related, however, there are GPL code in newlib root directory, 


1) can we confirm that newlib subdirectory is not infected?  which gnu official statement can certify it? 


2) if I only build baremetal metal newlib, is GPL code used? Can i say newlib I build is non GPL related?


Thank a lot.


Best Regards,
Douwa
