What, dbscripts use _foo variables ?
Doesn't that completely defeat the guideline we have in PKGBUILD man page :

       If you need to create any custom variables for use in your build
       process, it is recommended to name your custom variables with an _
       (underscore) prefix. This will prevent any possible name clashes with
       internal makepkg variables. For example, to store the base kernel
       version in a variable, use something similar to $_basekernver.

It is the PKGBUILD who should use _foo syntax to avoid clashes.
If dbscripts does it also, it's not avoiding clashes, it's asking for clashes :)

However, if dbscripts used things like $realpkgname $pkgbuild_pkgname
or whatever, it would be fine. If a pkgbuild also defined these, it
would be pkgbuild's fault of not following the guidelines.

This should definitely be fixed.
