The plan was to completely redo the build system in 5.1.  At least one
of the goals of that process it to build shared libraries (when the
architechture allows) so that the resulting binary set can be much
smaller.  Improving modularity of the build system is also a goal.

Yes. Very slow.  Takes about an hour or so on my 'puter to do a clean
build.

For small changes, I just do gmake5 and copy the binary from dist.<foo>
to wherever it would live in <target>/grass5/.  Somewhat tedious to be
sure.  When libraries change, it's another matter...
