Debugging shows that the access function used to check

It does return proper results for the 'nul' file in the old msvcrt.dll
but in newer libraries it returns EINVAL for the nul file.

I would recommend to consult with MinGW-W64 maintainers first: it may be
appropriate to handle this in mingw's wrapper for the access function.
In any case, they should be informed about this weird regression.

Cheers.

Thanks for your help Alexander. I've reported this to MinGW-W64 and the 
problem has now been solved in MinGW-W64, commit 
df15931c0d2c250218c68d71ec35bac61f84e1be.

Best regards,
