It doesn't do so well on a Macbook Pro (2.9 GHz Intel Core i5)! it used
about 147% cpu (i.e. the 2 physical cores) and took 8 minutes.
Much the same results with -gnatp -O2 as with the switches reported on
the website, not that I know whether they'd be appropriate for this
machine. (I see that the source code comments say "Note that this
version is compiled with full Ada checks enabled, and optimization
turned off", which isn't the case as reported).
This was with GCC 8.0.1 20180309, which required
Create_Lightweight_Thread's body to be seen before use.
