Intel has:
error #6752: Since the OpenMP DEFAULT(NONE) clause applies, the PRIVATE,
SHARED, REDUCTION, FIRSTPRIVATE, or LASTPRIVATE attribute must be explicitly
specified for every variable. [N]
>From the OpenMP 3.0 specification:
"The default(none) clause requires that each variable that is referenced in the
construct, and that does not have a predetermined data-sharing attribute, must
have its data-sharing attribute explicitly determined by being listed in a
data-sharing attribute clause." ("2.9.3.1 default clause")
Cf. also "2.9.1.1 Data-sharing Attribute Rules for Variables Referenced in a
Construct", which lists the variables which have "predetermined data-sharing
attributes"; in the example, it only affects "i" ("The loop iteration
variable(s) in the associated do-loop(s) of a do or parallel do construct
is(are) private.")
