Files included into other files (i.e. mostly .h, but also a few .c) are
particularly problematic, because they will be used from the source tree, if
the #include doesn't have directory component - the current directory will
always be searched first. In this case initdb on David's machine failed,
because the paths from the wrong pg_config_paths.h was used.

I think we should try to detect included files, due to the nasty and hard to
debug issues that creates. I've spent quite a bit of time helping people to
debug such issues.
