cygwin has a new, faster symlink files,
which are not supported by mingw nor by clisp,
but by the underlying cygwin libc only.
clisp supports the old winsymlinks .lnk files, so clisp supports all.
But mingw build tools will fail.

Yes, this asks for trouble.
Using the old textformat CRLF is not supported anymore, you may only create
a mount point for this dir with the text option.
But bash and most of the coreutils do not support it anymore.

This cannot be. Default is now unix eol. Only via mount you may create
textmode translation, but I rather think a mingw tool created those
files.

grep 2.3 is pre cygwin-1.7 where we did the switch.

You may try setup-legacy.exe to update your old cygwin-1.5 installation
where CRLF is still supported.
But better get rid of the textmode files under cygwin.
