bug#21789: 25.0.50; Can' build Emacs (my first build since GIT migration)

["Vincent Belaïche" <vincent.b.1@hotmail.fr>]

Dear Glenn,

I don't think that my problem is the toolchain.

But git was not configured for setting attributes to configure.ac to have LF
EOL's. So when configure.ac was pulled from repo it got native EOL's, ie
CRLF, and that was the root cause IMHO.

As per your suggestion, I think that what could be tested is that :

   perl -e 'print "\n"'

will output an LF, and not a CRLF.

For instance on my MSYS console I did this :

 $ if perl -e 'print "x\n"' | grep -U '^x$'> /dev/null; then echo "ok"; else echo "not ok"; fi
-| ok
$ if /c/Programmes/Perl64/bin/perl.exe -e 'print "x\n"' | grep -U '^x$'> /dev/null; then echo "ok"; else echo "not ok"; fi
-| not ok

In the former case the MSYS perl is used, so the verdict is OK, and in
the latter, that is the native MSW perl that is used, so the verdict is
NOT OK.

   Vincent.
