#include sys/file.h
(sys_access): Provide our own implementation which recognizes D_OK.
(is_exec): New function.
(stat): Use it.
(init_environment): Set TMPDIR to an existing directory.
Abort if none of the usual places is available.
(sys_rename): On Windows 95, choose a temp name that
includes the original file's base name and use an explicit loop
rather than calling mktemp.  Only attempt to unlink the newname if
the rename fails, rather than second-guessing whether the old and
new names refer to the same file.
