No, the pre-processor would _only_ have access to what is in the _base_ X11R6
installation.  The distinction is important.

The fact is that the vast majority of software in pkgsrc uses GNU configure.
Whether it's a deficiency or not that it tries to make the most featureful
software by using everything available in the environment is debatable, but it
is usually a concern only for software packagers that desire building the same
package consistently regardless of what's in the environment.  But that's what
we do in pkgsrc.
