_SHValidateUNC is defined in libshell32:

The other error might be a bug in MinGW-w64, or it might be a bug in your
compilation options. Do you have a SSCCE <http://sscce.org/>?

This looks like GCC 4.8.2, not 4.9.

In general, Windows has very complicated system DLL search stuff. This
includes winsxs, which is so complicated you should never muck with any of
it yourself, and let Windows handle it.
Anyways, on Windows 7 x64 Pro SP1, I've got a 32-bit crtdll.dll in some
winsxs directory, and one in SysWOW64. This last directory is definitely
searched for system DLLs in 32-bit applications (just check with Dependency
Walker). I don't know where you get the information this is not the case.
