Hi,
Node.FS.Base.Rfindalldirs is used for include flag generation and lookup of
directories from *PATH vars. It might occur duplicate paths of various
reasons (eg. after variable substitution) in the return value from
Rfindalldirs. Wouldn't it be neat to uniqify that list to avoid duplicate
include flags for example?
