[GRASSLIST:5319] Compilation error in r.mapcalc

[Tom Russo]

I'm running Grass5.7 on FreeBSD 4.x, which still uses GCC 2.95.  When I updated
today and tried to build I got a compilation error in r.mapcalc.  Turns
out that in Monday's commit to map3.c, a variable declaration was inserted
after the first executable line in a block --- something that GCC 2.95 
considers a syntax error but GCC 3.x does not.

The attached patch fixes it by moving the declaration of "handle" before
the call to setup_region.

Could someone commit this?
