  Priority:  normal           |  Milestone:  6.1

 For example:

 powerpc-rtems6-g++ -E -P -v -dD empty.cc 2>&1 | grep GNU_SOURCE

 Yields:

  /opt/rtems/6/libexec/gcc/powerpc-rtems6/10.2.1/cc1plus -E -quiet -v -P
 -D_GNU_SOURCE -Dmpc750 empty.cc -dD
 #define _GNU_SOURCE 1

 This is a GCC configuration bug. The reason is that the RTEMS GCC
 configuration includes gnu-user.h.
