It's 4 bytes, all right.

  (gdb-611) show architecture
  The target architecture is set automatically (currently hppa1.0)

The funny thing is, gdb 6.1.1 "maint print registers" says that
r19 is 4 bytes long, but "info reg r19" has special code to print
all 8 bytes of it.

I'm still kinda dubious, but if it's okay with randolph that the
debugger quietly operates in 32-bit mode, it's okay with me.
I would do something like this:

  gdb_test_multiple "info reg r19" "$name" {
    -re "r19 deadbeefbadcadee ..." {
      pass "$name (64 bit)"
    }
    -re "r19 "badcadee ..." {
      pass "$name (32 bit)"
    }
  }
