New parameter in GCC

[Harry Trinta]

I don't need to declare a variable to store the value which will be
passed in the compilation?

for example, I created a new compilation command:
fip-host =
Joined RejectNegative Common Var (host_ip_adress)
Set the host ip adresses that  the gcov uses to send informations about coverage


I do not need to declare the variable host_ip_adress somewhere?
How do I access the value passed in the compilation?

Thanks,
Harry
