Temporary directory for GPS

Hello,Is there a way to set from GPS a temporary directory used by gnatmake for the "-C" switch (or maybe others) ?If it is using the TEMP environment variable, maybe there is a way to override this ? I looked in "17.2 Environment Variables" of the GPS users' guide but did not find that (kind of a GPS_TEMP variable).For obvious reasons, I wouldn't like to hard-code a path into an "-C=xxxx" switch for open-source project files.TIA_________________________________________________________
