Ok, cool, I finally got it to compile, thanks for the help.

However, it doesn't produce an executable.  It generates an
executable, but without the correct permissions set.  

I changed them with chmod, moved it over to the board, and ran it, but
it gives me

$ chmod 777 irq_handle
$ ls
irq_handle
$ ./irq_handle
./irq_handle: 1: Syntax error: newline unexpected (expecting ")")

I guess the make didn't produce a binary?  Or is this error saying
something else?
