          Issue ID: 15646
           Summary: Unresolved symbols when using m32mscoff with Windows
                    subsystem
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: major
          Priority: P1
         Component: druntime
          Assignee: nobody puremagic.com
          Reporter: erikas.aubade gmail.com

The example windows application given at http://wiki.dlang.org/D_for_Win32
works fine when compiled with the default OMF runtime, but when compiled with
-m32mscoff it gives the following error

wintest.obj : error LNK2019: unresolved external symbol _MessageBoxA 16
referenc
ed in function _WinMain 16
wintest.exe : fatal error LNK1120: 1 unresolved externals
--- errorlevel 1120

It also seems to explicitly require a WinMain function--giving a similar
unresolved external symbol error--whereas with the OMF runtime, it seems to
function fine with void main() {}
