static programs are less suitable in a multiuser system or a system
where several applications use the same code. I mean if you had 10
different Ada programs or 10 users using the same program it would be
far better to have a dynamical program which can use the libraries. So
10 static programs may eat 4 Mb RAM each => 40Mb while the dynamic can
take say 2Mb => 20Mb and the library takes perhaps 2Mb  resulting in
22Mb.

Until gnat gets a part of gcc which is distributed on the major Linux
distributions (looks to happen now) it is probably smart to have a
static binary so people can "try out" the software. However I expect
that in the future one should make .rpm and .deb packages so that one
can make dynamic programs easily installable. :-)

No, but you should read about this on www.fsf.org and search the net. I
really wish some atterney could write "Software licenses and
implications for Computer Dummies" so one could easily understand what
to do. Maybe there already is one?
