Found the answer in one of your old postings:
http://gcc.gnu.org/ml/gcc-bugs/2000-04/msg00151.html

Original code by Claus Fischer:

but I'd invert this to dummy __restrict__:

#if __GNUC__ <= 2 && __GNUC_MINOR__ < 91
#define __restrict__
#endif

unless we really have to worry about gcc 1, in which case:

#if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 91)
#define __restrict__
#endif
