Similar to this, I was just going to suggest why don't you set the 
GRASS_FONT_CAP environment variable to a path that *is* writable. Then 
g.mkfontcap, and all the modules that use the fontcap, will simply use 
that instead of the fontcap in $GISBASE/etc. This mechanism is explicitly 
designed for the situation where a user doesn't have write access to 
$GIBASE/etc and needs to override the system fontcap file.

However, I don't think this is a good solution if the installation is 
required to be available to other users on the same Windows machine as the 
writable path will likely only be available to that user, if I understand
