Hm I see that NGREG is defined in Linux kernel in "include/uapi/linux/elfcore.h" as:
----------------->8----------------
#ifndef __KERNEL__
...
#define NGREG ELF_NGREG
#endif
----------------->8----------------

Then in its turn ELF_NGREG is defined for ARC in "arch/arc/include/uapi/asm/elf.h" as:
----------------->8----------------
#define ELF_NGREG	(sizeof(struct user_regs_struct) / sizeof(elf_greg_t))
----------------->8----------------

And since kernel's UAPI is meant to be exported to user-space I would expect NGREG to
be available for ARC and all other users of UAPI.

So might be a better solution would be to just include "elfcore.h" in jack's "dbus/sigsegv.c"?
I'll give it a try locally and if that works I'll send a patch upstream.
