Win64, SUBSYSTEM:WINDOWS and friends

[Michael]

MS linker by default allocates console window for programm if he 
see a main function as entry point and not allocates if he see a 
WinMain function as entry point.

So, if I don't want ugly console window for gui app, I can 
specify SUBSYTEM:WINDOWS linker flag and change a main to WinMain.
But I want to use ENTRY linker flag and do not modify source code.
With ENTRY flag a executable successfully compiled, but crashes 
at startup.

Any valid D Way workaround?

When compiling without modification in source.

library.
