by the way... I'm just having a look at an old build I did on a windows box
using msys and al old mingw (3.4.5)... It did compiled susccessfuly and it
did output libHalf.dll.a and libHalf-6.dll in the /bin folder... but the
libHalf.dll.a is waaaaay smaller than the one I got now. Also,
libhalf.lahas nothing BUT libHalf-6.dll...
It definitely looks like configure is going bananas because of the cross
build environment...
