See section "Scope" in the reference manual:
     http://www.rapideuphoria.com/refman_2.htm#42

| A namespace identifier has local scope. It is known only within the file
| that declares it, i.e. the file that contains the include statement.
| Different files might define different namespace identifiers to refer to
| the same included file. 

When your library 'mss.ew' also contains a line such as
     include odbc.e as ODBC

then your program should work as expected.
