I finally spent time in gdb figuring out what's going on.

The problem is that dash tries to convert c:/windows to an absolute
path, since it doesn't start with /.  I suppose I could teach dash to
recognize [letter]:/ as absolute paths, although that makes dash larger,
and puts a burden on me (since I can guarantee upstream dash won't
accept such a patch).

Me neither.  And since you can use /cygdrive/c, not c:/, I won't bother
to fix it.
