Comment (by glynn):

 Replying to [comment:21 neteler]:
 > I tried again but don't see a difference in the NULL file size:

 Check that the patch applied successfully, that compilation was
 successful, and that r.mapcalc is using the new libgrass_raster.so, not
 e.g. an installed version.

 The first two can be confirmed by running "strings" on the library and
 confirming that GRASS_COMPRESS_NULLS appears in the output. The last can
 be confirmed with e.g.
 {{{
 ldd $(which r.mapcalc)
 }}}
