# compiler
CC = gcc
# compiler flags:
# -g        tells the compiler to produce symbolic information that a debugger
#           (like gdb) needs.
# -Wall     tells the compiler to print warnings about pretty much everything.
# -pedantic checks that our code is portable to other C compilers
# -Ox       Optimize at level x

# for debugging:
CFLAGS = -g -Wall -pedantic
# for speed:
#CFLAGS = -O2 -Wall
