Source code changes of the file "depcomp" between
libisofs-1.5.2.tar.gz and libisofs-1.5.4.tar.gz

About: libisofs is a library to create an ISO 9660 filesystem, supports extensions like RockRidge or Joliet, makes bootable ISO 9660, and records file attributes which are of interest for data backups.
