The core file structure for the Utah 4.3BSD and OSF1 ports on the
PA is a mix between traditional cores and hpux cores -- just
different enough that supporting this format would tend to add
gross hacks to trad-core.c or hpux-core.c. So instead we keep any
gross hacks isolated to this file. */

I would not expect this to be of use to any other host/target, but
