Yes, I have the same problem

Isn't it unbelievable that the developers are not interested in fixing such
an evident and important problem?
Anyway, following your recommendation :
* I found the geoserver WKT for 900913 from Demo->SRS list->900913 (see
below):
* Saved in the file : EPSG_900913.wkt
* run the following command :
gdal_translate -a_srs EPSG_900913.wkt img1.tif img2.tif
no matter if i choose "force declared" or "reproject", the resulting is the
same, the image is offset...
any ideas where I might be wrong?
servet
the geoserver WKT :
