Hi. I don't understand how to build nrf_drv_saadc.c with gcc. I'm getting this error in the EVT_TO_STR() macro:

I guess it could be my CFLAGS to blame, but I can't easily compare to what the SDK does, because there's no gcc Makefile for the saadc example project.
[edit]
Here's my project's Makefile:
