These files have Unix line endings in the repository, hence it's best
to configure subversion accordingly.  Karl prepared a config file

  http://tug.org/texlive/svn/config.txt

already.  See http://tug.org/texlive/svn/setup.html (item 5) for more
information about installation.

Lines like 

 *.m4   = svn:eol-style=native
 *.sh   = svn:eol-style=native

should better be changed to

 *.m4   = svn:eol-style=LF
 *.sh   = svn:eol-style=LF

Files processed by regular expressions might be problematic if they
have DOS line endings.  AFAIK all Unix tools, even if compiled under
Windows, expect Unix line endings.  For instance, a regexp supposed to
match spaces at the end of a line / *$/ will not match with DOS line
endings because it's assumed that a line ends with LF. 

Even worse, I just converted linebreaks in a Perl script on Linux from
LF to CRLF.  As a result, the script can't be executed because the
shebang line isn't recognized anymore.  The shell strips trailing
spaces at the end of the line but the CR is left over.

Thus I think that many files in the Build tree should better be
checked out with Unix line endings on all systems.

BTW, if you don't have a subversion config file but the files you
checked out have DOS line endings, then I would assume that
"svn:eol-style=native" is subversion's default for non-binary files.

If this is true I could imagine that Karl's config file can be
significantly smaller.  It has to cover only the exceptions then.
