The newer versions of 'bash' packaged with Cygwin no longer unconditionally ignore CR characters in line endings as previous versions did. There are several ways to avoid the problem: Ensure that the files on disk actually have LF and not CRLF line endings. If you used a native windows app like winzip to unpack the tarball in conjunction with binary-mode mounts then that would cause the problem; use Cygwin's tar command instead. OR Unpack the files into a directory mounted as textmode. OR Set the igncr shopt in bash to make it ignore CR characters. The first of the three is by far the best route, as textmode can cause all kinds of strange failures, especially on a large and complex build system like gcc. See the Cygwin mailing list archives for the extensive and numerous threads on this topic. Brian
