I did post on MameWorld and received a link to a thread with the answer. The answer here actually wasn't the answer though.

Still, it pointed me in the right direction.
In armcore7.c, there is a line that read:
#define VERBOSELOG verboselog
I changed it to this:
#define VERBOSELOG(x) verboselog x
So now it compiles, but has some trouble linking. I'll probably post a follow-up on MameWorld too later today.
