Subject: rast problems dealing with null maps on DEC Alpha (Linux)

Platform: Linux/Alpha64
Linux distro: Debian
linux cpu: Alpha
Xwindows version: XFree 4.1.0
Xwindows manager: KDE 2.x
TclTk version: tcl/tk 8.3
grass downloaded at: Baylor site
grass binary for platform: I compiled the sources myself
grass sources source: no, I got a source code package from the server, 
5.0.0pre2
c compiler name: gcc

Anything to do with floating point raster maps with null map on a DEC Alpha 
causes a 
floating point exception... FIX taken from source of Grass 4.2.1 with FP + 
NULL patches is to not use NaN to mark nulls in floating point maps but 
rather to use FLT_MAX...

I could probably make a patch available if required... but if is #if 0 
marked on code I am using here...
