Is it safe to interrupt (Ctrl + C) while building a port or kernel?

[Антон Клесс]

Sometimes, while building process of some port or system kernel are in progress, you suddenly remember that you did something wrong and have to stop, solve your mistake and start one more time.

Is it clear to interrupt the building process just by pressing Ctrl + <C>?

If it's so, do I need to run "make clean" before I start "make" one more time?


Thank you!
