I've attached patch to mingw-w64 that replaces _access in msvcr110/120 and
ucrtbase with Liu Hao version (for me it is too big for inline).
After patching mingw-w64 (and before building) please go to mingw-w64-crt
folder and execute
aclocal
automake
to regenerate makefiles.
This patch changes only lib files -- it should work.
Regards,
Mateusz

Subject: [PATCH] Add _access function that works for nul file to msvcr110/120
and ucrtbase libs
