"failstar" sounds like a name for a cruise liner from the 80s. As "*" isn't a desirable part of directory names, just name the whole thing "fail/", the core parts being stored in "fail/core/". Additionally fixing two build system dependency issues: - missing jobserver -> protomessages dependency - broken bochs -> fail dependency (add_custom_target DEPENDS only allows plain file dependencies ... cmake for the win) git-svn-id: https://www4.informatik.uni-erlangen.de/i4svn/danceos/trunk/devel/fail@956 8c4709b5-6ec9-48aa-a5cd-a96041d1645a
