The shapefile format by itself is projection-less. They need an
associated .prj projection file if another piece of software is to
use them in a projected environment without manual projection entry.

If the shapefile is known to be in the current GRASS location's
projection, but lacks a .prj file, you can use "v.in.ogr -o" to skip
the mis-matched projection check and force the import.
