Patch applied.  I'm not sure it's a good idea to add -D_COMPILING_NEWLIB
to all targets.  I don't know how RTEMS handles it, but in Cygwin it's
only used in very special cases in which we have clashes between newlib
and Cygwin definitions (for instance when using _off_t vs. off_t).
Are you sure that all cases in which `#ifdef _COMPILING_NEWLIB' is used
in newlib are also feasible for RTEMS?
