Minimal test case

Here's an attached quite minimal testcase for this issue.

The makefile builds a tiny DLL using mingw/gcc, and generates an import
library, both using --out-implib with ld and using dlltool. Then the makefile
builds two test exes that links to the created import libraries - both exes run
just fine on windows.

The batch script msvc.bat builds the same test exes using the MSVC command line
tools, both with and without the /OPT:REF flag, against both of the created
import libraries. The ones built with /OPT:NOREF work fine, while the ones
built with /OPT:REF fail.

For comparison, it also creates an import library from the .def file using
lib.exe, and links against it. For the exes built against this import library,
both versions work.
