I just saw that there is a new configuration option when compiling

To what does this refer to exactly?
Well, in fact it doesn't do much just yet. There is code in libgretl's
gretl_matrix.c to use vectorization (either SSE or, if available, AVX)
when adding, subtracting or multiplying suitably sized matrices, but for
now this is commented out in preparation for the 1.9.14 release.
After release we'll experiment with this some more. Jack and I will be
working on this sort of thing next week, along with some computer
scientist colleagues. Once we have our own ideas more clearly formulated,
we'll no doubt be asking people to experiment and tell us what they find.
