I did not build MinGW 4.3.0. I got it from the official MinGW site
(gcc-4.3.0-20080502-mingw32-alpha). I have also found that on www.equation.com
there are even newer versions (binaries), like 4.3.3 with OpenMP 2.5, 4.4.0
with OpenMP 3.0 and MinGW 4.5 compilation snapshot. They seem to work fine with
OpenMP. They aren't present on the official MinGW site. Why?
