When using portupgrade, I use the MAKE_ARGS variable inside of pkgtools.conf. I have variables set for '*' as well as many ports. However, I want to be able to undefine a variable I set previously in the '*' entry. I found a mailing list thread from 2007 for rt36 that mentions using -U<variable> with make, but make complains saying that U is an illegal option, and the man page says nothing about -U being an option. Even if it were an option, I'm not sure how BSD make would handle the situation of defining a variable with <variable>=<something> or -D<variable> and then later undefining it with -U<variable>. So is there a way to do this either via pkgtools.conf or via make itself? Thanks, Naram Qashat
