> grep uses the C runtime that comes pre-installed on the system.

Quite right. The fact that the OS itself is (usually) written in C means that nearly every OS-using computer has a C runtime.

As an aside, consider executable file sizes in the Windows world, where the OS does not provide its C library to other programs. Many programs in Windows include their own versions of the C library, increasing their sizes.
