Moving msesysintf from implementation uses to interface uses in

fixes the issue.
I know what causes the crc problem: the fact that msesysintf declares
routines as "external name" in the implementation which aren't
declared as "external name" in the interface. This is supported for
Delphi-compatibility, but is quite ugly (it also causes wrappers to
be
generated because it is possible that units which were compiled after
only the interface was parsed may already contain calls to the non-
external but regularly mangled Pascal name).
That means all "external name" declarations should be in interface
section?
That's the most efficient, yes (and also what we do in the RTL).
Alternatively, you can manually create the wrappers in the
implementation (so you add separate external declarations in the
implementation and then call these from regular Pascal implementations
of the interface definitions), so the compiler doesn't do this for you
and subsequently change the interface "declaration" into the external
definition.
