I didn't touch any of the buildfiles , even didn't touch the PG's source code and didn't reinstall or upgrade Xcode. Just configure the PG and gave 'make' and I got this error.

Ok

Thanks and regards

This codepath would only be reached if the buildsystem determined that memset_s
was available so something is fairly wrong here.  Did you change any builfiles
after running configure?  Re-install or upgrade XCode after running configure?

memset_s and memset have the same prototype, and are functionally equivalent,
but memset_s have certain properties which are required in this codepath.
