Syntax: __auto(list-of-variables)
For Fortran, __AUTO(list-of-variables) is also accepted.
The __auto clause can appear on a parallel directive (including parallel for/do, parallel sections, and Fortran parallel workshare directive) or on a task directive.
The __auto clause on a parallel or task construct directs the compiler to automatically determine the scopes of the named variables in the construct. (Note the two underscores before auto.)
If a variable is specified in the __auto clause, then it cannot be specified in any other data sharing attribute clause.
