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