- Hacked for SunOS 4.1 by gnu@cygnus.com. In 4.1, the
- compiler actually produces the correct address (we
- don't need to fix it up). I made this code adapt so
- that it will offset the symbol if it was pointing at
- an int-aligned location and not otherwise. This way
- you can use the same gdb for 4.0.x and 4.1 systems.
-
- If the parameter is shorter than an int, and is

- don't believe it! Offset the parameter's address to
- the tail-end of that integer. */
