I thought it was broken in more= like 2005 not 2011. You?re only hope is to bisect the tree down to the cha= nge that caused it? It's been broken since at least the last binutils import and probably longer since the inane ld behavior of activating --sysroot only when built with a specified sysroot is from upstream. The fix is trivial, just merge r257268 and r257530 to the branch you are using. -- Brooks --xHFwDpU9dbj6ez1V Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (FreeBSD) iKYEARECAGYFAlNiSaZfFIAAAAAALgAoaXNzdWVyLWZwckBub3RhdGlvbnMub3Bl bnBncC5maWZ0aGhvcnNlbWFuLm5ldDY1NUQ1MTlDMjZBNzgyRTcyNTI5OUJGMDVE OEU4QkU5RjIzODFBRDQACgkQXY6L6fI4GtSUuwCfQ2Nz6YJ4HgYusrNSoArrpSK8 LEIAn2Bd8gDAxqU2qHYWT8VTLXOh3kcX =t2pm -----END PGP SIGNATURE----- --xHFwDpU9dbj6ez1V--
