+
+
+GCC detects that we call 'restrict' as param name in function
+signatures and complains since both params are called 'restrict'
+therefore we use __restrict to denote the C99 keywork
+
+This only happens of uclibc since this code is not excercised with
+eglibc otherwise we will have same issue there too
