* use 64-bit file system calls (Linux, Darwin)
  * use 32-bit [sic] uid/gid calls (Linux)

- morestack support for 5l and arm runtime
- argsize support in 5c, 5l, ar and nm. assembly code from 5a

- explicit cond execution constants
- fix 5l output to use %d instead of %ld so that negative
  values show.
- added a lot of code to arm/asm.s. runtime entry code almost
