These, along with http://hobbes.nmsu.edu/download/pub/os2/dev/util/mzfntcfgft_runtime_20130104.zip
should hopefully be all the extra DLLs required for running the newer Mozilla builds based on the 17ESR and 24ESR releases.
Source code is available via RPM from netlabs.
Note that if you have already installed the DLLs from moz_required_dlls_v1.zip there is no need to install these.
