Evidently, the FSF is now claiming that all object code produced from GCC 4.2.2 and later is GPLv3-licensed, and only their exception permits you to distribute executables compiled using an "Eligible Compilation Process" under the terms of some other license. I wonder if they make this claim even if -nostartfiles, -nostdlib and/ or -nodefaultlibs options are used? Regards, -- -Chuckhelp
