Attention packagers: the default version of gcc on many distros happens to generate Wine binaries which make some copy protection schemes unhappy. At the moment, gcc-3.3.x, gcc-3.4.x, and gcc-4.2.x are known to work; gcc-4.0.x is known to not work. Please check the compiler you use when building wine packages and make sure it's one of the good ones.
To really check, find a retail copy of Photoshop CS or CS2 (not 7 or CS3) and install from cd-rom. If it aborts silently near the end without offering to activate the product, you have an unsupported compiler, and users of your packages might run into trouble with apps protected with safedisc.
