memmem isn't a standard C function, and some libraries don't have it, notably Microsoft's.

newlib's memmem seems to be the same as glibc's, but is under a BSD 3-clause license instead of LGPL. An older version of newlib's memmem (prior to 2019-01-01) has the license "Permission to use, copy, modify, and distribute this software is freely granted, provided that this notice is preserved", and is still highly optimized and much better than a naive implementation.

Of course, bundling it would no longer be quite so "free".
