In order to get this into the Xastir compile properly we need an
"xastir/src/shapelib/" directory, not "xastir/shapelib/", correct?

"xastir/src/shapelib/" would put it at the same level as rtree and
allow us to have Xastir's configure set up everything for us.  I
seem to remember that Make has troubles with multiple top-level
subdirs.  This would avoid that problem.

I put the shapelib-1.2.10 sources into "xastir/src/shapelib/" and
may attempt to merge it into autoconf/automake.  If I get the
install to work with/without Shapelib already installed I'll check
it into CVS.

I'll have to go study after that to see how to link it in
statically, which Tom suggested is the right thing to do in order to
avoid problems with incompatible shared libs in the future.
