Just to remind you: I reported a similar problem when 1.7 just came out.
Maybe it helps in identifying the problem.

As you can see I did not specifiy the ellipsoid parameter:

Sorry, but you didn't give this command line in your first message.
the gdal error message was: ERROR 6: Failed to initialize PROJ.4 with
`+proj=tmerc +lat_0=49 +lon_0=-2 +k=0. 9996012717 +x_0=400000
+y_0=-100000 +ellps=airy +datum=OSGB36 +units=m +no_defs'. unknown
elliptical parameter name
Your command works for me (GDAL 1.7.1) :
$ gdalwarp -s_srs EPSG:27700 -t_srs EPSG:4326 essai.ecw essai.tif
Creating output file that is 42102P x 22239L.
Processing input file essai.ecw.
