Subject: Ignore source units that have already been included

There is the possibility that the same source file could be discovered
twice, if the same folder is included multiple times as a library folder
or if symbolic links are used that link to already-included files. These
duplicate source files are now ignored, to prevent erroneous 'duplicate
definition' errors from being generated.
