Comment (by glynn):

 Replying to [ticket:800 ferrouswheel]:
 > In r.random/support.c there are sprintf calls which cause buffer
 overflow errors when the map names and mapsets are too long. I've attached
 a patch to replace with snprintf.

 snprintf() isn't in C89; if you want to use it, you need to add a
 configure check, and provide an alternate in case it isn't available.
