Annex A, paragraph 3 states:
The implementation shall ensure that each language defined subprogram
is reentrant in the sense that calls on the same subprogram perform as
specified, so long as all parameters that could be passed by reference
denote overlapping objects.
I believe subsequent discussions (mentioned in the AARM) have confirmed
that the 'objects' effectively include external files (although strictly
this is implementation defined).
The ARM 83 did not define what had to be task-safe, and I suspect this
is the source of the problems with some Ada 95 implementations.
