It looks like mingw is broken .... x lrwxrwxrwx 0 root root 0 Nov 08 20:34 sourceware-mirror-newlib-cygwin-d14714c69/newlib/libm/machine/x86_64/feclearexcept.c -> ../../fenv/fenv_stub.c: Can't create '\\\\?\\D:\\opt\\rtems\\rsb.git\\rtems\\build\\arg7ndxwm1\\sourceware-mirror-newlib-cygwin-d14714c69\\newlib\\libm\\machine\\x86_64\\feclearexcept.c' This is due to this change from Joel in newlib around 4 months ago... https://github.com/RTEMS/sourceware-mirror-newlib-cygwin/blob/master/newlib/libm/machine/x86_64/fesetenv.c I though I added logic to the RSB to handle these cases but it looks like we have another case that needs handling. The reason the failure happens is the destination directory for the link does not exist and so the file copy fails. On Unix system the link is a path attached to the node and so does not need to exist until you access it. The order in the tar file means the link appears before the destination directory.
