--- Comment #5 from Chris Johns <chris at contemporary dot net.au> 2013-04-02 06:28:32 UTC --- A cygwin cross-compile also fails as it is a 32bit host. The failure is not specific to Linux. This means RTEMS users have problems building from source on Windows as cygwin currently us not working and MinGW has issues (gcc-4.7.2 contains path elements great than the Windows max. limit and this effects MinGW utils, eg rm).
