Yes, this bug is reasoned by preparations to support multilib in w64 crt. Now
we generate the target specific object files for 64-bit into the 'lib64'
folder. This reasoned the problem we talking about.
In the past we put our object (and library) files into <target-triplet>/lib
folder, which has hidden the problem.
But for me it is ok to fix this for 4.5 (beside we need to work-a-round this
for version before 4.5).

Yes, just make out of this '#define STANDARD_INCLUDE_DIR "/mingw/include"'
