I did not read *all* of it, but it seems the ODBC documentation
contains no such madness. So my guess is that the Microsoft
"implementation" of SQL-CLI that is ODBC defines that handles cross
compilation units. IMHO the other implementations of ODBC better
follow that, or I'm not sure it is worth supporting them in

And on a nitpicking level, ODBC has a relationship to ISO/IEC
9075-3:1995, not 9075-3:2006 :) But indeed I guess that 9075-3:1995
contains the same language.
