I played around a bit more, this is what I found. (I should note this is under Windows 7 x64, and I used VS 2010 32-bit to compile in case it should matter) cd /d E:\Argyll\Argyll_V1.7.0_2014-10-10\bin echo -t? -?? cd /d E:\Argyll\Argyll_V1.7.0_2014-09-01\bin echo -t? -?? Both "echo"s return "-t? -??" (without the quotes). cd /d E:\Argyll\Argyll_V1.7.0_2014-10-10\bin ccxxmake -t? ccxxmake -?? Prints help but without technologies. ccxxmake -? Prints help with technologies (I actually wasn't aware of that :)). With the older Argyll CMS development version (2014-09-01) the behavior is reversed: cd /d E:\Argyll\Argyll_V1.7.0_2014-09-01\bin ccxxmake -t? ccxxmake -?? Prints help with technologies. ccxxmake -? Prints help without technologies. Florian.
