# Specify which compiler to use
CC = gcc

# Specify options to give to the compiler when translating source to object
# -g		Generate debugging code, for use with gdb
# -Wall		Enable all warnings
# -O1		First level of optimization
# -std=c99	Adhere to C99 language standard
# -pedantic	Reject programs using non-standard extensions
