how to compile a 64-bit .dll on windows with lcc-win?

Using Windows 7 64-bit and lcc-win32

2 source files:

Hello.c
HelloImpl.c

The following:

lcc -shadows -unused -v -IC:\lcc\include -I"C:\Program Files\Java\jdk1.7.0_45\include" -I"C:\Program Files\Java\jdk1.7.0_45\include\win32" -g2 %1.c
lcc -shadows -unused -v -IC:\lcc\include -I"C:\Program Files\Java\jdk1.7.0_45\include" -I"C:\Program Files\Java\jdk1.7.0_45\include\win32" -g2 %1Impl.c
lcclnk.exe -map %1.map -dll -o %1.dll %1.obj %1Impl.obj

Produces a 32-bit .dll

but this:

lcc64 -shadows -unused -v -IC:\lcc\include64 -I"C:\Program Files\Java\jdk1.7.0_45\include" -I"C:\Program Files\Java\jdk1.7.0_45\include\win32" -g2 %1.c
lcc64 -shadows -unused -v -IC:\lcc\include64 -I"C:\Program Files\Java\jdk1.7.0_45\include" -I"C:\Program Files\Java\jdk1.7.0_45\include\win32" -g2 %1Impl.c
lcclnk64.exe -map %1.map -dll -o %1.dll %1.obj %1Impl.obj

Produces:

Entry point DllMain not found
Use the -entry command line option

After the linker command and a 2K .dll filled with zeros !

What am I doing wrong ?
