Trouble pulling in libm

I assumed that and actually am pulling in several libraries successfully myself so I did not expect this issue.
I am trying to refine things in terms of my issues.  I noticed on closer inspection that the math.h file inclusion does not appear quite right since it says the round function definition is implicitly defined.

Because I was working with sockets and, at the time, trying to get a telnet daemon running.

It is superfluous to this issue, but it shows how to add multiple libraries, since you can never eat just one (cultural reference).
