Sorry, all, I'm not making a Makefile for each user-contributed
test program.

However, this is how I compiled Dr. Thomas Hamelryck's test.cc 
on a Solaris machine using SunOS; you'll need to substitute in 
the all-caps []'d parts with the actual values extracted 
from your Makefiles.

[CC] -c -ggdb3 -Wno-unused -DUNIX -fpic -D_REENTRANT -I[GPPINCL] -I[LIBGISTHOME/include] test.cc

[CC] -I[LIBGISTHOME/include] -L[LIBGISTHOME/lib] test.o -o test -lbtree -lrtree -lnptree -lgist -lm -lstdc++

(I'm not claiming this is the shortest command line that will
work.  Merely that it is the one that worked for me.)
