BTW, this is what Ayush is trying to do:

https://gcc.gnu.org/ml/gcc-patches/2016-07/msg01302.html

https://gcc.gnu.org/wiki/replacelibibertywithgnulib

It would be great if someone could review his patches. I cannot approve them 
myself.

You could even ask him to look next at replacing the libiberty version of 
regex.c with gnulib's in GCC. It is on his TODO list.
