  Using our internal random number implementation...
  Determining whether or not we are on an EBCDIC system...
  Nope, no EBCDIC, probably ASCII or some ISO Latin. Or UTF-8.
  Checking how to flush all pending stdio output...
  Your fflush(NULL) works okay for output streams.
  Let's see if it clobbers input pipes...
  fflush(NULL) seems to behave okay with input streams.

  Determining whether we can use sysctl with KERN_PROC_PATHNAME to find executing program...
  I'm unable to compile the test program.
  I'll assume no sysctl with KERN_PROC_PATHNAME here.

  I'm unable to compile the test program.
  I'll assume no _NSGetExecutablePath here.
  It appears we'll be able to prototype varargs functions.

  Run make depend now? [y]

  <p>Executing the above makedepend line gave a message <code>make: *** No rule to make target 'clist'.  Stop.</code>. Any hints to debug this? Much appreciated!</p>
