use option -std=c99 or -std=gnu99 to compile your code - c

Question

I've the following error:
'for' loop initial declarations are only allowed in C99 mode
use option -std=c99 or -std=gnu99 to compile your code.
How can I add this option to my makefile? This is my makefile: (I think that this option should be in the first lines of the makefile)

You have a line:
CFLAGS += -DBOARD_$(shell echo $(BOARD) | tr a-z A-Z)
You can add it to the end of this line so it reads:
CFLAGS += -DBOARD_$(shell echo $(BOARD) | tr a-z A-Z) -std=c99
