[BUG]: Unable to execute programs using wine-vc

Describe the bug

I am trying to execute programs compiled with wine-vc. I get the following error:

Could not execute the program
Compiler returned: -1
Compiler stderr
<spawn /usr/bin/wine ENOENT>

I enabled debug output, and this is probably from a cwd that doesn’t exist: "cwd":"mp/compiler-explorer-compiler2022723-53-1dkihet.ihfx"

I assume this is caused by this: https://sourcegraph.com/github.com/compiler-explorer/compiler-explorer/-/blob/lib/compilers/wine-vc.js?L54

So, uh, what is that line of code there for? Am I doing something wrong?

Steps to reproduce

I am trying to build a docker container with compiler-explorer and MSVC. The easiest way to reproduce is to use that:

https://github.com/edmcman/docker-msvc-compiler-explorer

Then try to execute any C++ program using Visual C++ 2005 or 2008.

Expected behavior

The program executes

Ok, that makes sense. I guess the better question is can that path actually ever start with Z: at this point?

Based on my limited reading of the source code, I don’t think it can, because that path will ultimately come from https://sourcegraph.com/github.com/compiler-explorer/compiler-explorer/-/blob/lib/base-compiler.ts?L266:5&subtree=true

filename() is always called “last minute” just before it’s passed to for example runCompiler() and similar functions where the inputfilename is a parameter to a compiler, https://github.com/compiler-explorer/compiler-explorer/blob/46cdf8f4a504e68591d1695eedc3ddfb791c88e5/lib/base-compiler.ts#L1591

Execution is working perfectly with those two commits!
