Hello Martin,

With this patch applied on top of Christophe's master branch:

diff --git a/libmultipath/dict.c b/libmultipath/dict.c
index ea273dd91962..ac9216c4c5f3 100644

 set_int(vector strvec, void *ptr)


I see a whole bunch of warnings appear (see below). Can you have a look at
this?

Thanks,

Bart.
