[Marc Glisse]

Hello,

understanding the testsuite is hard, but this patch seems to work. The 
idea is that vect_double and others don't tell that vectors are supported 
with these options, just that there exist options that enable vectors. 
They are thus useless outside of a directory like vect/ that adds those 
flags.
