New Revision: 250616
URL: http://svnweb.freebsd.org/changeset/base/250616

Log:
  Use an ugly hack to get around bootstrapping problems when building
  clang on head between r239347 and r245428.
  
  The former revision introduced CLOCK_PROCESS_CPUTIME_ID as a clock id
  for the clock_gettime() function and friends, but it was only added in
  <sys/time.h>, not in <time.h>.  Any program including <time.h> would
  therefore not be able to use CLOCK_PROCESS_CPUTIME_ID, even though the
  value of _POSIX_CPUTIME indicates its existence.  The latter revision
  synchronized the defines again.
  
  Work around this problem by defining the id on the command line for the
  particular .cpp file that needs it.  If the id ever changes value, this
  hack will need to be updated.
