CC = gcc

# The CFLAGS variable sets the flags for the compiler.  CS107 adds these flags:
#  -O0         do not optimize generated code
#  -std=gnu99  use the C99 standard language definition with GNU extensions
#  -W<various> configures which diagnostic warnings are given
CFLAGS = -g3 -Og -std=gnu99 -no-pie -fno-pic -Wall $$warnflags -fno-toplevel-reorder -fno-builtin -fno-inline -fno-stack-protector -D_GNU_SOURCE -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -fcf-protection=none
export warnflags = -Wfloat-equal -Wtype-limits -Wpointer-arith -Wlogical-op -Wshadow -Winit-self -fno-diagnostics-show-option

# The LDFLAGS variable sets flags for the linker and the LDLIBS variable lists
# additional libraries being linked. The standard libc is linked by default
# and we require no additional libraries or flags, so these are empty.
