  Five years of EROS data towards the Small Magellanic Cloud have been searched
for gravitational microlensing events, using a new, more accurate method to
assess the impact of stellar blending on the efficiency. Four long-duration
candidates have been found which, if they are microlensing events, hint at a
non-halo population of lenses. Combined with results from other EROS
observation programs, this analysis yields strong limits on the amount of
Galactic dark matter made of compact objects. Less than 25% of a standard halo
can be composed of objects with a mass between 2 10^-7 Msol and 1 Msol at the
95% C.L.
