msvc builds use "response" files to hold the includes, defines, and
source file.  That's the @"bin\msvc\debug\hello.obj.rsp" part of the
command-line above.

If it successfully compiled, it deletes the .rsp file, but if the
compile fails, it leaves the .rsp file there and you would be able to
see the defines and includes passed in.
