Yes, this is an annoying problem.  When the CLOCK_PROCESS_CPUTIME_ID
support was originally added, it was only put in sys/time.h, not in
time.h.  So any application that includes the latter will not be able to
use the define.

There are multiple possibilities to solve this, but I'm thinking of
putting a -DCLOCK_PROCESS_CPUTIME_ID=15 on the command line for older
versions of -current...
