This is a native i686-pc-mingw32 bootstrap on Windows XP SP2 with NTFS.
The confusing "Permission denied" error ultimately comes from the
behavior of CreateFile() on Windows, which is to set ERROR_ACCESS_DENIED
as the failure condition when no other error number particularly
applies. Windows does not have an equivilent to the Unix EISDIR.
If this is a bug, it is a bug that has existed for almost two decades,
that is probably impossible to work around sanely in the C library. GCC
could add special Windows-specific handling to provide a more
descriptive error message, but its probably not worth it.
