Re: [Gumstix-users] Robostix code problem

Dave,
	your right about it being a problem, but this is GPL code from another
source.
I have since changed it to be put_c and this solves the compiler error,
but the resultant hex file dosn't work as expected.
I am going to put in a LED_TOGGLE to see if the code is atleast runing
in a loop in main.
