*    Officially DEC, IBM, HP, Sun5.8, Sun5.9, and  SGI are not supported any more and 
     they were not tested for this release. The windows is supported for HDF-EOS 
     and HDF-EOS5 but not Toolkit
**   Packaged as Red Hat Linux Enterprise
***  IA64 platforms does not support -m32 flag. Therefore HDF-EOS/TOOLKIT cannot be 
     installed in 32-bit mode in these machines.
