Do not rely on Perl symlink status, for MSYS perl. * automake.in (require_file_internal): Ensure presence of symlink target file; MSYS perl symlink doesn't return an error status when the file could not be created (copied, on this system). Fixes symlink.test failure. Signed-off-by: Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
