Problem with program dig_P_area_att() in the DIG library

Hi.

I have a problem in using one of the routines in the DIG library. (GRASS4.0)
I used the routine

    dig_P_area_att(map,area)

in a program. The #include files were
    gis.h
    digit.h
    dig_head.h
    dig_defines.h
    dig_structs.h
    V_.h

The rest of the program compiled fine, but the loader gave an error message:
    ld: undefined symbol
    _dig_P_area_att
The program compiled fine when I commented out this routine.

I went through the various library files: src/mapdev/Vlib , diglib, etc.
The only reference to this function was in file frontend . I do not see what
went wrong.

Could someone please comment on this?
Thanks.
