Cygwin 1.5 sometimes, but not always, failed on rename("dir1","dir2")
when "dir2" exists.  Beef up the m4 tests to more reliably
detect at least one of cygwin's bugs, in spite of not knowing
why the rename only failed sporadically (thankfully, cygwin 1.7
does not have the bug).  Meanwhile, although NetBSD needs to
share the hard link workarounds, it does not need the trailing
dot and directory workarounds, so split the m4 test into two
separate feature checks.

* m4/rename.m4 (gl_FUNC_RENAME): Split cygwin bugs into two
checks.

The Autoconf macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and
AC_TRY_RUN have been obsolete since Autoconf 2.55, and each use
can evoke a warning from autoconf when run with -Wobsolete
enabled.  They were declared obsolete for good reasons (see
the `AC_FOO_IFELSE vs AC_TRY_FOO' node in the Autoconf manual,
recently renamed to `AC_ACT_IFELSE vs AC_TRY_ACT'), and we
