This question is more appropriate to the gcc-h...@gcc.gnu.org mailing list which is for help using and building gcc, the gcc@ list is for development of gcc. Please take any follow-up to gcc-help, thanks Have you tried simply building without --with-sysroot? That option causes the compiler to look for all system headers in /my/root instead of the default locations such as /usr. If you want to relocate the compiler to a system without /my/root then using sysroot is the wrong way to go.
