* configure.in (RUBY_DTRACE_POSTPROCESS): dtrace version SUN D 1.11
introduces a check in the dtrace compiler to ensure that probes
actually exist. If there are no probes, then the -G step will
fail. As this test is only being used to determine whether -G is
necessary (for instance, on OSX it is not), adding a real probe to
the conftest allows it to succeed on newer versions of dtrace.

* configure.in (SIZEOF_STRUCT_DIRENT_TOO_SMALL): remvoed. It is
only used for readdir_r.
* dir.c: removes NAME_MAX_FOR_STRUCT_DIRENT. It is not right way
to detect maximum length of path len. POSIX require to use
fpathconf(). IOW, it might have lead to make a vulnerability
using stack smashing. Moreover, readdir() works enough for our
usage.
* dir.c (READDIR): removes an implementation which uses
readdir_r() and parenthesize in a macro body correctly.
* dir.c (dir_read): removes IF_HAVE_READDIR_R(DEFINE_STRUCT_DIRENT
entry), it is used only for readdir_r().
* dir.c (dir_each): ditto.
* dir.c (glob_helper): ditto.
* dir.c (READDIR): removes entry and dp argument.
* dir.c (dir_read): adjust for the above change.
* dir.c (dir_each): ditto.

of -Wclobbered warnings.
* include/ruby/defines.h: include setjmpex.h here becase setjmp.h is
included from win32.h via intrin.h, winnt.h, and so on.
