I'm going to have to make a note in the documentation about this, since it comes
up frequently. Compression filters are disabled whenever you set the variable
NO_COMPRESSION, *even if you give it the value 0*. In retrospect, I probably
should have given the value 0 special treatment; I'm reluctant to change it now,
however, since this is one library feature that's hard to test.

Please try omitting -sNO_COMPRESSION=0 and see what happens.
