Copy/purge bug!

[Bas van der Vlies]

cfengine 2.0.3

The problem is in copy/purge action. If the destination directory contains
a directory that is not in source directory it will be removed. In this
cfengine version all files/directories inside the offending directory will
be removed, but NOT the top most directory. This error occurs on UNIX
platforms where you are not allowed to delete the current directory, eg:
        mkdir /var/tmp/a
        cd  /var/tmp/a
        rmdir /var/tmp/a 

This is allow on Linux, but not on IRIX, SOLARIS and AIX.

I made a quick patch to solve this problem:
void PurgeFiles()
....

        chdir(".."); /* HvB: Bas van der Vlies */
        if (rmdir(filename) == -1)

....
