Say, are you sure that qecvt() exist?
I've searched all header-files and didn't find anyone of the 
cvt-functions capable of handling long double.
Is it a brand new feature/function in MinGW (my MinGW is a few months old).
I also searched MSDN, but didn't find qecvt()
(I can find ecvt(), but that is not interesting.)
