figured that some non-libc startup code must still be in snn.lib so I included
that as a library, but then I get this

C:\dm\lib\snn.lib(constart)
Error 42: Symbol Undefined _main
C:\dm\lib\snn.lib(wconstar)
Error 42: Symbol Undefined _wmain
C:\dm\lib\snn.lib(wwinstar)
Error 42: Symbol Undefined _wWinMain 16

I'm not sure why it would be trying to import all of those. I use WinMain as the
start function, and am using the following

dmc -c -mn -WA -NL helloworld.c
link /NOI /DE /XN /NT /ENTRY:WinMainCRTStartup /A:512 /L/exet:nt/su:windows
helloworld.obj kernel32.lib user32.lib snn.lib
