And it is.

Then something is wrong in the MSVC-specific parts of the makefile's.
When compiled with MinGW, emacsclientw invoked without arguments shows
a GUI dialog with an error message and an OK button.

If you could find out what is wrong in the MSVC build, please tell.
Most (if not all) people who track Emacs development on MS-Windows use
MinGW, so we don't have MSVC to try that.
