These wont be detected though present in vista+. So, the build tries to use the replacement functions even on vista, which should have been ok except for the declaration mismatch with some mingw headers for vista+ --- such a mismatch is not expected, so is very likely specific to some versions of mingw, I don't know. The failure to detect a function, but then find a mismatch while building is a good example of the limitations of AC_CHECK_FUNC -- one being, headers not included (cannot be included) during the test.
