I believe you are asking for a preprocessor level solution in gcc? Unforunately AFAIK there is no such support in gcc.

I changed from [2] to [3] recently but didn't notice the problem right away. I wonder whether it would be better to always use the srcroot-relative path when compiling? What is the benefit of the full path? Or maybe it should be controllable somehow? Regards, Simon ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
