I see that this can lead to confusion. To resolve this, the way I prefer 
most would be not to use

     .if defined(VAR)

when checking for boolean variables, but to use

     .if defined(VAR) && !empty(VAR:M[Yy][Ee][Ss])

The other thing is: As soon as a package has successfully passed the 
pkglint check without errors and warnings, the chance for remaining bugs 
of this kind is very small, as the commonly used variables are already 
checked for this.

Currently there are only 46 warnings of this kind left in the complete 
pkgsrc tree (without wip).
