There is an open issue that the current --with-sysroot relocatability computation is different than what GDB_AC_WITH_DIR does. We should fix that regardless. I've left that as a separate issue. [We should resolve it before checkin, but at this point I'm willing to just experiment until we know what the right fix is.]

OK, I just use such change, and regenerate the configure under autotools 2.68.

I just test your patch, and it works Fine under Windows!!! (gdb relocation works OK!)

Thank you!!
