It seems to me that what's really wanted here is to change the add_sysroot flag for the C++ path (all of the C++ paths?), rather than adding special code to detect paths starting with the sysroot and reinterpret them. And so making configure detect when the --with-gxx-include-dir setting starts with the sysroot and adjusting the flag accordingly in that case would be a cleaner solution - that way it would be obvious that the semantics of the relocation are exactly the same as for other sysrooted paths, whereas it isn't when the relocation goes through different code paths in the compiler. -- Joseph S.
