Onr my 64-bit Windows 10 box Sequential_IO (String) Write makes a 4 
bytes prefix (32-bit length, I guess). E.g. "abcd" it does 4, 0, 0, 0, 
'a', 'b', 'c', 'd'. I think it depends on whether the GNAT is targeted 
for 32- or 64-bit and not on the actual OS. What a mess!

All this is just wrong. It should have been 'a', 'b', 'c', 'd'. Though 
RM conveniently tells nothing about its semantics, the name and 
parameters profile suggests one of S'Write, no constraints read/written.

But honestly who would ever care? The package is clearly obsolete and 
under/ill-specified. Should never be used anywhere.
