testsuite on mingw

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

When cross-compiling from cygwin to mingw, the testsuite is created by
cygwin with \n line endings, but executed by a mingw executable which
produces \r\n line endings.  I'm installing this to normalize mingw output
in the testsuite, so that it doesn't fail practically every test just
because of the line ending differences.

2006-09-04  Eric Blake  <ebb9@xxxxxxx>

        * doc/m4.texinfo (Changeword): Skip test on mingw, where the
        native echo is braindead.
        * checks/check-them (strip_needed): Ignore \r in output.  Now the
        testsuite will pass when cross-compiling from cygwin to mingw.
