 * Definitions to generate Intel SVR4-like core files.
 * These mostly have the same names as the SVR4 types with "elf_"
 * tacked on the front to prevent clashes with linux definitions,
 * and the typedef forms have been avoided.  This is mostly like
 * the SVR4 structure, but more Linuxy, with things that Linux does
 * not support and which gdb doesn't really use excluded.
 * Fields present but not used are marked with "XXX".
