I've activated this in CVS-HEAD, a couple of minutes ago.

Should you experience weird compiler errors complaining about undefined
types, on code that has been compilable so far, you probably are still
using one or more of the deprecated types.

As a short/mid term band-aid, in such cases, you can try to configure
RTEMS with 

The long term solution however is to modify your code to using the POSIX
types. Thus changes however might not be functional with former versions
of RTEMS and with older GCCs/newlib's.
