Subject: r.sun crash on 64bit

Hi,

here again as bug report. r.sun crashes on 64bit CPUs:

It crashes in INPUT () at main.c:656
              if (z[i][j] == UNDEFZ || o[i][j] == UNDEFZ || s[i][j] == UNDEFZ)

Here a Spearfish test script:

ELEV=elevation.dem
TMP=$$
SLOPE=$TMP.slope
ASP=$TMP.aspect
r.slope.aspect elevation.dem as=$TMP.aspect sl=$TMP.slope --o
r.mapcalc global_shadow.rad=0
DAY=055
r.sun -s elevin=elevation.dem aspin=$TMP.aspect slopein=$TMP.slope day=$DAY \
      beam_rad=bs_rad.$DAY diff_rad=ds_rad.$DAY refl_rad=rs_rad.$DAY


(gdb) r -s elevin=elevation.dem aspin=10066.aspect slopein=10066.slope day=055
beam_rad=bs_rad.055 diff_rad=ds_rad.055 refl_rad=rs_rad.055
