unused variable in chase_symlinks

On cygwin, I'm getting a lot of these warnings (on CVS head M4, one for
each of the 42 gnulib tests):

 creating test-isnanl-nolibm.exe
./.libs/lt-test-isnanl-nolibm.c: In function `chase_symlinks':
./.libs/lt-test-isnanl-nolibm.c:499: warning: unused variable `rv'

due to unused code being generated by libtool.  OK to commit?  Also,
ltmain.m4sh has a lot of whitespace problems (space-tab and end-of-line
whitespace) that emacs flagged, is it okay to fix that in a separate commit?

        * libltdl/config/ltmain.m4sh (func_emit_cwrapperexe_src:
        chase_symlinks): Avoid compiler warning.

Don't work too hard, make some time for fun as well!
