Daniel,

In fact, one of the changes in 6.0 has been the stripping out of the
non-GDAL based raster readers.  This means that WMS layers were already
depending on GDAL otherwise the rasters returned from the remote servers
would not be readable.  This made me more comfortable with the VSI
dependency in mapwmslayer.c. :-)

I made this requirement clear in the WMS Client documentation yesterday,
but I didn't think to check if it is reflected in configure or other docs.

Best regards,
