It is library/Mmakefile:378, specifically these line:

    # Don't use Unix style paths with the Microsoft C# compiler.
    ifeq ($(CSC),csc)
    MLOBJS += ..\runtime\mercury_dotnet.cs
    else
    MLOBJS += ../runtime/mercury_dotnet.cs

The above is a workaround for the fact that --link-object does not yet
do any path conversion.
