--- Comment #19 from Esme Povirk  ---
Setting DETACHED_PROCESS in compile_cs prevents console windows from being
created for csc.exe on Windows and Wine, but in Wine we get a console window
for mcs.exe, so there's more that needs fixed. It probably requires a change to
how we call mcs.exe.

Ideally I'd like to get rid of this "RedirectStandardOutput" thing, is there
any way we can call mcs.exe so it'll inherit handles and not create a new
console window?
