mono AOT on Windows exe gives me an DLL

I'm on Windows and I'm trying ahead of time compilation on Main.exe that's been compiled with the Mono C# compiler gmcs (also tried mcs).

>mono --aot Main.exe

but that produces a Main.exe.dll and I want an executable. Is that possible?

Update:

I intercepted the AOT/build process by write protecting Main.exe.dll and now I have a mono_aot_FZKP2U.o but still no luck:

>gcc -o Main2.exe mono_aot_FZKP2U.o
/mingw/lib/libmingw32.a(main.o):main.c:(.text+0x104): 
undefined reference to `WinMain@16'
collect2: ld returned 1 exit status`

Update 2009-10-30:

After reading Jb Evains answer I once again tried to runt the Main.exe.dll with mono with no success.

The Mono AOT compilation process doesn't create an executable. It indeed creates a library. Mono automatically picks up the AOTed code if possible, you just have to run mono Main.exe like you would normally do. You can check by specifying the environment variable MONO_LOG_LEVEL=debug if Mono picks up the native code.
