...s to one representing "external unknown functions". It has edges to everything *might* be visible outside this unit, and has edges to itself from everything might call external functions having not appeared in this unit. External functions already declared in this unit have their own callnodes and should have explicit edges to/from others. It gets its improvement if we have some "pre-knowledge" of external function already declared in this unit. For example, we are sure that standard libc function "strcmp" never calls *anything*(no matter what linkage it might be...
