Copy purge bug in cfengine 2.0

[Bas van der Vlies]

On IRIX (use native c-compiler) i experience the following bug:

  /var/copy
    dest=/var/dest
    r=inf
    purge=true

If in the dest directory contains a directory that is not in copy we get
a segv. I have change the image.c and patched the function 

PurgeFiles(...)
....
          if (S_ISDIR(statbuf.st_mode))
             {
             struct Tidy tp;
             struct TidyPattern tpat;

             printf("Bas gaat het hier mis\n");
             tp.maxrecurse = 2;
             tp.tidylist = &tpat;
             tp.next = NULL;
             tp.path = filename;

             /* Bas van der Vlies fixes segv on IRIX
             */
             tp.exclusions = NULL;
             tp.ignores = NULL;

                Regards
