Hi Mathieu,

Here is Upstream's Makefile:

CC = gcc
CFLAGS = -Wall
DEBUG = -g 
LDFLAGS = -lm
OPT = -O3
(...)
velveth : $(OBJ) 
        $(CC) $(CFLAGS) $(OPT) $(LDFLAGS) -o velveth obj/tightString.o obj/run.o obj/recycleBin.o obj/splay.o obj/splayTable.o obj/readSet.o obj/crc.o $(Z_LIB_FILES)

As you see, $(OPT) comes after $(CFLAGS), and is set to -O3. We therefore have
to override it directly.

Have a nice day,
