Samba for VMS V2.0.3 does not use the shipped VMS C-RTL's but uses the
backport library which then was used to build the Samba-C-RTL. This was done to
make the binary distributions work on any OpenVMS system since VMS 5.5-2
(VAX) or 6.0 (Alpha). (BTW: The Samba C-RTL itself was built referencing other
shared images like LIB$RTL from those old systems).

To build the Samba C-RTL, I used the backport library from DEC-C V6.0
which (as far as I remember - can't check this now) has a C-RTL Version > 7.0
(i.e. __CRTL_VER *is* >= 70000000). You should upgrade to DEC-C V6.0 or higher
(or at least get a DEC$CRTL.EXE (?) from DEC-C V6.0 - this shared image
tells the compiler about the C-RTL version (__CRTL_VER) ).
