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