Package: libxdo-dev

Hi maintainer,

<xdo.h> isn't directly usable in C++ source files because it doesn't wrap
functions in extern "C" {} when __cplusplus is defined. This means that a
call to, say, xdo_init will resolve to the name-mangled version of the
function, but libxdo.so provides an unmangled name.

It looks like the X headers handle this with the _XFUNCPROTOBEGIN and
_XFUNCPROTOEND headers in <X11/Xfuncproto.h>, which you could use.
Alternatively, you could just conditionally wrap the header in extern "C"
yourself.

Thanks,
