As of version 0.62, TC does support literals as program identifiers
(PROGRAM-ID).

Unfortunatly, according to the standard, the meaning of the call
convention is implementor-defined.

TC uses the STDCALL (C call convention) as a default, so the STDCALL
keyword is NOT required.

Since the SPECIAL-NAMES section is only partially implimented, so
the CALL-CONVENTION clause is not implimented.

Sounds like a boundary (4 bytes) bug of some sort.
