I have reproduced this problem with r6841 on win2003/x64.

  val mb_ = _import "MessageBoxA" : MLton.Pointer.t * string * string *

This needed to be changed to _import "MessageBoxA" stdcall, though.

The problem persists with this simplified compile line:

> mlton -link-opt "-mwindows" -default-ann 'allowFFI true' clicktest.sml


Once the -mwindows is removed, the test program works. I'm currently
investigating what '-mwindows' does to the program. Do you need it?
