Bug 51009: _X_RESTRICT_KYWD fix for g++ 4.6 & later on Solaris
g++ 4.6 & later on Solaris set the __STDC_VERSION__ define to indicate
C99 mode to expose C99/Unix03 functions in the system headers, even
though they don't recognize the C99 restrict keyword, as explained in
http://gcc.gnu.org/ml/gcc-patches/2010-05/msg01308.html
Thus we avoid using the restrict keyword here if __cplusplus is also
defined, falling back to the __GNUC__ case using __restrict__ instead.
