Module:    rtems
Branch:    master
Commit:    2d5c48691453a05ffb3a264f75e71490166f819a
Changeset: http://git.rtems.org/rtems/commit/?id=2d5c48691453a05ffb3a264f75e71490166f819a

Author:    Nick Withers <nick.withers at anu.edu.au>

Use fixed-width C99 types for PowerPC in_be16() and co.

Also use the const qualifier on the address pointer's target in in_*()

Closes #2128
