I understand that situation. How could it be solved?

1-Adding another configure option --short-in-memory or perhaps=20
--with-huge-data? In that case, if --with-double=3Dno --with-huge-data=3D=
yes were =20
specified, then nn/csa would not be built; if only --with-double=3Dno, th=
an=20
floats would be converted to doubles and vice versa.

2-Even if --with-double=3Dno, we always convert floats<->doubles, but rel=
y that=20
users know what they are doing and would not call the nn/csa based griddi=
ng=20
algorithms? If they would they would do it just once -- learn by error.

3-Or making --with-qhull=3Dno by default? I vote against this last one :(=
)

The second option seems reasonable to me.

It could be run by configure, then users would just sent the result to us=
=2E
Stupid woman!(1) don't you see that we already have this? It's called=20
config.summary!
