Maybe we could allocate a temporary large array on the heap if the readlink call fails with the 1000 byte buffer on the stack?

Just FYI, even PATH_MAX may not exists on some system (AFAIK, hurd, allowed by posix).
And though st.st_size is mentioned in readlink man page, it may not return useful value.
