Well, I tried also the tarball version cairomm 1.10.0 and the problem
is exactly the same.
I think it comes from cairomm itself - it looks as if
cairomm-vc100-d-1_0.lib doesn't export that constructor.
It is not listed in the .def file generated by gendef and dumpbin
-exports on the library (which is generated in the build process)
doesn't list it either.

The calling function Cairo::Surface::get_device(void) is listed as
?get_device at Surface@Cairo@@QAE?AV?$RefPtr at VDevice@Cairo@@@2 at XZ
correctly.

The constructor is defined in the device.h file line 91 in the section
external dependencies.
explicit Device(cairo_device_t* cobject, bool has_reference = false);

very strange... do you have any further suggestions?
