Since pow is much, much slower in mingw 3.x than in mingw 2.x, other people
started to search for a solution. I found this interesting enough:
http://www.willus.com/mingw/ (look at "Some Fast Math Functions" at the end
of the page).
Thus here, there are two possibilities: to match the standards and provide
full-proof math functions, like it is done in current mingw (and in R,
consequently)... but sacrificing speed. Or, to rely to online assemble...
