Comment(by cmbarton):

 After combined work by Anna, Helena, and me, I've found a way to fix this.
 Remove all references to gvl_data_align in ../lib/ogsf/gvl_calc.c

 gvl_data_align is called in 2 places in gel_calc.c, once for viewing
 isosurfaces and once for viewing slices. It needs to be removed in both
 places. Since these are the only places it is called AFAICT, the function
 can be removed too.

 No one (including the developer who's name is listed on the gvl_calc.c
 source code) seems to know what gvl_data_align is supposed to do. BUT I
 don't know if this will cause a problem on any other platform, including:

 Mac OS X 10.6
 Linux
 Windows

 So testing is needed. If this works on all platforms, it needs to be
 propagated to all GRASS versions now in development.
