ld/ChangeLog: * configure.in: If <dlfcn.h> can't be found, try for <Windows.h> * configure: Regenerate. * config.in: Likewise. * plugin.c [!HAVE_DLFCN_H && HAVE_WINDOWS_H] (dlopen): Provide trival LoadLibrary-based replacement for Windows systems. [!HAVE_DLFCN_H && HAVE_WINDOWS_H] (dlsym): Likewise trivial replacement based on GetProcAddress. [!HAVE_DLFCN_H && HAVE_WINDOWS_H] (dlsym): Likewise FreeLibrary. * sysdep.h: Don't infer presence of <dlfcn.h> from ENABLE_PLUGINS anymore, use its own guard.
