That seems likely.  With mmake under Cygwin we run that paths through
cypath -m; we probably don't do that for mmc --make (which is what the
csharp grade requires).

The intention here was that setting --host-env-type=cygwin should cause
it to do the Mercury compiler to do the correct path translation, but
I don't think that is implemented.

I think we also require a --csharp-compiler-type option similar
to the --c-compiler-type option, because mono and csc differ in the
their treatment of paths depending on whether you are under Cygwin
or MSYS or the native command prompt on Windows.  (See bug #222).
