In grass 6.4:
GRASS_OVERWRITE=1

r.mapcalc "result = rand(1,100)"

100%

r.mapcalc "result = rand(1,200)"
 ##ok, raster result has been overwritten
 100%


In grass7.0:
GRASS_OVERWRITE=1

r.mapcalc "result = rand(1,100)"

 100%

r.mapcalc  "result = rand(1,200)"
###  raster 'result' hasn't been overwritten

I have to setting GRASS_OVERWRITE variable and r.mapcalc command in
the same line as you suggest:
GRASS_OVERWRITE=1 r.mapcalc "r = rand(12,24)"
in this case it works in both version.  Strange behaviour IMHO.
