Ivan,

GDAL plugins are not complete gdal libraries.  They are just a single
driver linked against GDAL and containing a GDALRegister_GRIB() entry
point.  Note that the short name for the driver in the DLL name has to
match in case with the registry entry point, so you need to name the
DLL gdal_GRIB.DLL if the entry pointis GDALRegister_GRIB().

The gdal/frmts/mrsid/makefile.vc includes a plugin target as an example
of how to build the MrSID driver as a plugin.

Normally GDAL looks for plugins in the directory indicated in the
GDAL_DRIVER_PATH environment variable.  On windows it also tries to
look in a gdalplugins directory under the directory containing the
currently running .exe.

I don't know if ArcGIS is otherwise adjusting the driver load path.

Best regards,
