commit 9dfdc96a81f384d8cbfb9d87212db1aec0a22d25

    tests: check if 'compress' is real or fake
    
    On Cygwin, 'compress' is provided by sharutils and is just a
    dummy script that is not able to actually compress (it can
    only decompress).  This fake 'compress' is not usable for
    our purpose - to create compressed tarballs.
    
    * tests/dist-formats.tap (missing_compressors): Count 'compress'
    as missing if it does not support the -c option.
