[Proj] gdalwarp EPSG:32662 problem

Sorry for cross posting. This seems like a proj4 issue but might be gdal 

I've run into a problem that I think is related to a change in the EPSG 
definition for EPSG:32662

The symptom is that the image after gdalwarp reprojection is about 20km 
south of where it should be.

old system is correctly aligned:

GDAL, released 2007/06/27
proj Rel. 4.5.0, 22 Oct 2006

# WGS 84 / Plate Carree
<32662> +proj=eqc +lat_ts=0 +lon_0=0 +x_0=0 +y_0=0 +ellps=WGS84 
+datum=WGS84 +units=m +no_defs  <>

new system is shifted about 20km south:

GDAL 1.9.2, released 2012/10/08
proj Rel. 4.8.0, 6 March 2012

# WGS 84 / Plate Carree (deprecated)
<32662> +proj=eqc +lat_ts=0 +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 +datum=WGS84 
+units=m +no_defs  <>

This indicates that the definition in proj 4.8.0 is wrong. Would the 
+ellps=WGS84 account for this shift?

Any thoughts on this?
