I would not adjust the test case to cope with systems which are not in 
line with POSIX. In the past RTEMS used the GCC tests to check that the 
implementation is in line with other systems. The RTEMS ticket is still 
open. There just needs to be someone who thinks this bug is important 
enough to fix.
