I haven't seen an official announcement, yet, so some clarification:

The source tree has been restructured.

* Basically, c/src/exec has been moved to cpukit
* Other parts from c/src/* have also moved to cpukit.
* cpukit can be built standalone and multilib'ed without having any BSP
present.

Have a look into cpukit/. the code you are looking for probably is
there.

This is a change in gcc/newlib and RTEMS interaction. sys/param.h has
become part of newlib. => You need a newer RTEMS gcc/newlib tool chain
(gcc-3.1 or gcc-3.2 from OAR's ftp are supposed to work).
