That will create a variable for you.

You #include "options.h" refer to the variable host_ip_address.

To be clear, this will give you a new variable in the compiler itself.
It will not give you a variable in the gcov program, nor in the program
you are compiling.  You will have to figure out some mechanism to get
the value to the point where you need it.  It's not clear to me where
that point is.
