Kai, just a few points here... He *IS* building a cross compiler. Now, I am under the impression that fixincs needs to be run on the standard C headers for a target board, because they often aren't 100% ANSI compatible, or need to be modified to reflect the different functionality that libgcc might provide compared to the OS vendors libs. So I have the idea that fixincs must be run on the vendor headers a) in order to build libgcc correctly and b) in order to have valid headers that will work with gcc after installation. I am also firmly convinced (because I've tried it over and over again) that fixincs will never be run on the files in $prefix/$target/include, only on the files in $prefix/$target/sys-include. Therefore, if the OS vendor headers are to be fixinc'd, they must be in sys-include. And if they aren't to be fixinc'd, why does fixincl.x have OS vendor specific patches for systems such as VxWorks? >The system-dependent headers, ie. specific for just the one PC, should be >put into the 'sys-include'. I can't make sense of this, I'm afraid, "Specific for just the one PC", to me means 'this one here on my desk but not that identical one on the next desk'. Unless these headers contain the hostname or other similar unique identifier I can't imagine what headers might meet this standard ?
