A symlink from a Unix-style path to a DOS-style path? That appears to
be the problem to me. It's a bad symlink. Unix programs will not work
properly with this symlink.

Then why don't you change the symlink to this path?

slash_adjust() only changes "\" to "/", which doesn't change the length
of the path. I assume that cygwin_conv_to_posix_path() can change the
length, thus it's a very different thing.
I think the Cygwin version of Vim should never see "C:/path" things,
thus converting all paths sounds like a good idea. Probably near the
start of mch_FullName(). However, I don't know if this breaks
something. I never use the Cygwin version.
