Nios® II 'alt_irq_register' warning



I'm trying to invoke an interrupt for some buttons on my DE2-115 EVM but I constantly getting the following warning (not error) about the 'alt_irq_register' command:

Description: Implicit declaration of function 'alt_irq_register' [-Wimplicit-function-declaration]

]Resource: hello_world.c, Path: /Interrupt_sw, Location: line 200, Type: C/C++ Problem]

I did (attached herewith) almost exactly as written in the C Example in the " Nios II Software Developer’s Handbook"," Chapter 8: Exception Handling", pages: 8-6 and 8-7.

What could possibly be the reason for that warning? (Again, I did exactly as Altera's example…)
