[GRASS-dev] Compiling problem after adding _()

[Carlos Dávila]

After change listed below in /lib/rst/interp_float/input2d.c modules 
r.resampl.rest and v.surf.rst don't compile.
-          G_fatal_error ("mask raster map [%s] not found", 
params->maskmap);
+        G_fatal_error (_("Mask raster map <%s> not found"), 
params->maskmap);

Error message is the same for both modules:
grass6/dist.i686-pc-linux-gnu/lib/libgrass_interpfl.so: undefined 
reference to `_'
collect2: ld returned 1 exit status

Is this normal?
