OK, Dave Cole, just pointed out that list is the wrong thing to use 
here. The CMAKE_C_FLAGS variable is supposed to be a string and not a 
list.   If you used list(APPEND more than once it would always fail. 
So, although odd that it has a space in it, it is benign.  You should 
treat the variable as a string and not a list.
