+ - Added Makefile for easier compilation.
+ - Set default PATIENCE to 10. This is because modern computer systems tend to
+   have frequent interrupts, so increasing this value increases benchmark
+   accuracy.
+ - Added support for setting key compile-time parameters using command-line
+   arguments to the compiler or Make. Parameters which may be set this way
+   include `ADVANCE`, `NCHUNK`, `NTRIAL`, `PATIENCE`, `RUNTM`, `STOPRT`, and
+   `STOPTM`.

  - `RUNTM`: The minimum time to run each trial, in seconds. HI64 will use this
