[GRASS5] Definition of main() in lib/vector/rtree

[Paul Kelly]

I was just re-compiling v.surf.idw and noticed a warning about the 
definition of main in libgrass_rtree.so being pre-empted:
cc -s -s  -L/usr/local/lib 
-L/indigo-disk2/grass/grass51/dist.mips-sgi-irix6.2/lib 
-I/usr/local/include     -DPACKAGE=\""grassmods"\" -o 
/indigo-disk2/grass/grass51/dist.mips-sgi-irix6.2/bin/v.surf.idw 
OBJ.mips-sgi-irix6.2/main.o OBJ.mips-sgi-irix6.2/read_sites.o -lgrass_vect 
-lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient 
-lgrass_dbmibase  -L/usr/local/lib -lgdal -lgrass_gis -lgrass_datetime -lz 
-lgrass_datetime -lm  -lz
ld: WARNING 85: definition of main in OBJ.mips-sgi-irix6.2/main.o preempts 
that definition in 
/indigo-disk2/grass/grass51/dist.mips-sgi-irix6.2/lib/libgrass_rtree.so.

I had a look there and there is a main() in lib/vector/rtree/gammavol.c 
and sphvol.c. As these files are part of the library and never called on 
their own it would seem to be OK to just delete the main() from these two 
files---anyone disagree?
