Yes.  Historically, different people have done newlib ports over the
years in Cygnus and there was a time when it wasn't standardized
where pieces belong.  Nowadays setjmp is put in the machine directory
and the syscalls are usually in libgloss.

Yes, the newlib code works with the ARM emulator in gdb.  No special instructions or warnings.

If your spell-check liked "funcitons", I figure "seperate" should have been ok. :)

No.
