No, that's no bug, just diagnostic messages with the new linker.

I'll check how to get rid of that if you want to get rid of it without
grep -v :)
But I don't think that is is easily possible to turn off these purely
diagnostic messages, without cluttering the source with those
__DLL_IMPORT declarations.
And I found no easy ld cmdline override solution. But I'll backcheck.

#ifdef BUILDING_DLL
# ifndef __GNUC__
# define __DLL_IMPORT __declspec(dllimport)
# else
# define __DLL_IMPORT __attribute__((dllimport)) extern
# endif
#else
# define __DLL_IMPORT
#endif
