Strictly speaking, access() (or _access()) isn't a documented part of
any Windows ABI. It's only documented as part of the C Runtime Library
for Visual C++, a different product. This is an important distinction,
while MinGW should support Windows APIs as documented by Microsoft,
it's not ment to be compatable with Visual C++. MinGW does use the same
runtime DLL as used by Visual C++ 6.0, but this is essentially just an
implementation detail, not ment as a compatibility goal. There are a
few of ways MinGW's runtime is incompatable with Visual C++ 6.0.
One of those ways is that the MinGW headers define R_OK, W_OK and X_OK.
That was a probably a mistake, but in order for the MinGW runtime to
be compatibile with both previous implementations and Windows Vista I
think this change makes sense.
