Comment (by duncan):

 We now check that relative paths do exist, eg:
 {{{
 include-dir: include
 }}}

 But we do not check absolute paths. The rationale is that relative paths
 are part of the package so if they're missing then we have a problem, but
 absolute paths are on the system and these might be just a list of
 possible paths that may exist on some systems and not others.

 Incidentally this would help in the original complaint
 {{{
 include-dirs: C:\Program Files\PostgreSQL\8.2\include, C:\Program
 Files\PostgreSQL\8.2\include\server, .
 extra-lib-dirs: C:\Program Files\PostgreSQL\8.2\include, C:\Program
 Files\PostgreSQL\8.2\include\server
 }}}

 We would get a warning:
 {{{
 Warning: 'include-dirs: Files\PostgreSQL\8.2\include' directory does not
 exist.
 Warning: 'include-dirs: Files\PostgreSQL\8.2\include\server' directory
 does not exist.
 Warning: 'extra-lib-dirs: Files\PostgreSQL\8.2\include' directory does not
 exist.
 Warning: 'extra-lib-dirs: Files\PostgreSQL\8.2\include\server' directory
 does not exist.
 }}}
