I've been trying to compile a trivial program (extern C int

no success.
I compile with dmd -debuglib= -defaultlib= -v -L=/INFORMATION
-betterC but optlink shows a lot of things from snn.lib being
pulled in and the resultant executable is about 12kb. I also
replaced object.d with an empty module.
If I pass /nodefaultlib to the linker I get warning 23: no
stack and __acrtused_con is undefined so the linker fails with
no start address.
Is it possible to completely remove the C runtime on windows,
and if so how? Sorry for the sloppily formatted post.
I recently created an issue that included an example that allows
you to compile a Hello World program on linux x64 without the c
standard library, druntime or phobos.

You can modify it to run on windows as well. I'm not sure if the
_start assembly implementation would be the same on windows. Try
it out and let me know how it works.
