Lorenzo,

Sorry about that ... my error.  I have fixed this in CVS, committed
the fix and replaced the beta tarballs and zip.

If you want to reorder the bands it is possible to do so with some tricky
steps.

Basically, build a .vrt file corresponding to the input file:

gdal_translate -of VRT bgra.tif bgra.vrt

Then edit the .vrt file with a text editor, and change the <SourceBand>
values around to the order you want.  For instance, change the
<SourceBand> for the first VRTRasterBand to 3, the 2nd to 2, and the
3rd to 1.

Then convert the .vrt file back into a TIFF file and it should be reordered.

gdal_translate bgra.vrt rgba.tif

Good luck,
