 -Wall -c -g 
 -Wall -O3 -c -g -Werror 

NOTE at the end of each line of options leave a space [0x20] This is to
prevent the last word merging into the file name on the command line. In
this case there is a space after the word "-g" and "-Werror". To check
it out move the cursor to the end of the two top lines and note that it points
to a space and not a character. When editing the option line just press the
space bar at the end of the line then save the file.
The current options are just a sample. You must provide suitable options for
your compiler with ../include paths ect. Above are two seperate option lines.
Swapping lines 1 and 2 changes the compiler options.
