The problem seems to have been related to the presence of a .prj file with
the .shp file.
using the command
gdalwarp -cutline .\shp -cl allROIs -cwhere "Item = 1642" .\1642\1642.bmp
seems to fail to compute cutline bounding box when there is a .prj file
present for the .shp and the target image has no georeference embeded as
with a geotiff. Here in this case I was trying to trim a .bmp so that was
that I think was the reason.
However remove the .prj from the .\shp directory and it works!
Alternatively, I can specify the -s_srs and -t_srs as the same and this also
works although it does throw a warning that the input vector layer has an
srs while the raster does not. As long as the two are in the same
projection. No problem I think.
