I was just working with a couple postdocs using GRASS 6.4.0 on Windows. We tried to enter the following command in the command line window in the layer manager
r.mapcalc newmap=if(oldmap<=18000,1,null())
This generated an error saying that it could not find oldmap.
If we did this in the MSys terminal (adding single quotes as needed there) it works fine.
r.mapcalc 'newmap=if(oldmap<=18000,1,null())'
I don't know if this is an error or if we were doing something wrong.
Maybe someone else more accustomed to GRASS for Windows can test.

I had a similar complaint for GRASS6.4.1 on Windows 7 running r.mapcalc from command console,
I don't remember exactly what the issue was but I will to try to check tomorrow.
