X_OK is only defined in system.h if it's not defined by system includes. On
mingw, X_OK happens to be defined by <io.h>.

The mingw developers have modified their include files to work around this
case, and you can get the old behaviour (X_OK is ignored) by compiling with
-D__USE_MINGW_ACCESS (see PR33281). I intend to commit a patch that makes us
build the compiler with -D__USE_MINGW_ACCESS, thus removing the problem.
I thus intend to close that PR. Zack, if you think we shouldn't use access() at
all, do you want to keep this PR open and change its title to reflect this
desired change?
