[m-users.] Java grade missing!!?!?

[Richard O'Keefe]

On the subject of --output-libgrades

% mmc --output-libgrades
mercury_compile:
`--host-env-type posix' is incompatible with `--csharp-compiler-type
  microsoft'.
% csc /help
Microsoft (R) Visual C# Compiler version 3.100.19.26603 (9d80dea7)
Copyright (C) Microsoft Corporation. All rights reserved.

This is Ubuntu 18.04, and the C# compiler is definitely the Microsoft
one, and they are quite compatible with each other.  Not even a home-
brew installation:
libmono-csharp4.0c-cil/stable-bionic,stable-bionic,now
6.0.0.313-0xamarin3+ubuntu1804b1 all [installed,automatic]
libmono-microsoft-csharp4.0-cil/stable-bionic,stable-bionic,now
6.0.0.313-0xamarin3+ubuntu1804b1 all [installed,automatic]
mono-csharp-shell/stable-bionic,stable-bionic,now
6.0.0.313-0xamarin3+ubuntu1804b1 all [installed,automatic]

So why is mmc unhappy?
