Nope. We cannot do this, we don't want this. It would mean that every gnulib-
derived <stdlib.h> file would provide the same macros and functions. This is
not compatible with gnulib's module system. It would mean that every package
that includes <stdlib.h> needs the replacements/overrides of _all_ functions
that are commonly declared in <stdlib.h>: both the declaration and - to avoid
link errors - also the code. No, we don't want to reduce the modularity
of gnulib that much.

It is not only "theoretically possible", it is the common case.
