Never mind I found a solution. For anyone else who has this problem all i did was add -langversion:experimental into the mcs compiler.

example:
mcs -langversion:experimental -target:library -out:`pwd`/Ultima.dll -r:System.Drawing.dll -nowarn:0618,0219,0414,1635 -d:MONO -d:ServUO -d:NEWTIMERS -nologo -optimize -unsafe -recurse:`pwd`/Ultima/*.c

This starts to look like a mono version problem. I've a different code base but added a piece with pattern matching and it compiled fine. (without any -langversion settings, anywhere). The type pattern stuff seems to be c# 7.x (https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/is)

If I try to figure out what I have:

This command might vary on distribution and installed things:
yay -Qo `which mcs`
/usr/bin/mcs is owned by mono 6.0.0.334-1

These should work distribution independent:
mcs --version
Mono C# compiler version 6.0.0.0

mcs --help
Turbo C# compiler, Copyright 2001-2011 Novell, Inc., 2011-2016 Xamarin, Inc, 2016-2017 Microsoft Corp

mcs [options] source-files
<snip>
-langversion:TEXT Specifies language version: ISO-1, ISO-2, 3, 4, 5, 6, Default or Experimental
<snip>

mcs -langversion:error
error CS1617: Invalid -langversion option `error'. It must be `ISO-1', `ISO-2', Default, Latest or value in range 1 to 7.2

I did this:

sudo apt install gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/ubuntu stable-bionic main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update
sudo apt-get install mono-complete

and was able to get the make to start.

To install the client binaries i had to do some extra wine work:

sudo dpkg --add-architecture i386
sudo apt-get -y install wget
wget -qO - https://dl.winehq.org/wine-builds/winehq.key | sudo apt-key add -
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
sudo apt-get update
sudo apt-get update
sudo apt install --install-recommends winehq-stable
wine --version
wine-4.0.2

And then found this post relating to older emulation scenarios:


So I applied that patch.

And... It started.
