--- Comment #5 from Jim Michaels <jmichae3 at yahoo dot com> ---
I am on windows. @var(n) means nothing on my platform please describe it in the
documentation.
I just tested mingw-w64 with the value 0 and with the value 12, and both give
me 1-threaded code.
yes, I included -O2
so, since "n" is not allowable, I am recommending the value 0 for auto or max
or max-1.
