GRASS 7.1.svn (bladen_stpft):~ > g.region -p
projection: 99 (NAD83(2011) / North Carolina (ftUS))
zone:       0
datum:      ** unknown (default: WGS84) **

Please try r68384 (datum string added to lib/gis/datum.table) and check if this is now correct:

GRASS 7.1.svn (nc_data_test):~ > g.proj -w
PROJCS["NAD83(2011) / North Carolina (ftUS)",
    GEOGCS["grs80",
        DATUM["NAD83_National_Spatial_Reference_System_2011",
            SPHEROID["Geodetic_Reference_System_1980",6378137,298.257222101]],
        PRIMEM["Greenwich",0],
        UNIT["degree",0.0174532925199433]],

Works correctly now.

g.region -p
