Checked again with link.exe from WinDDK 2600.1106:

4. link Hello.bin /nologo /subsystem:console /entry:start /out:Hello.exe /fixed:no /map:Hello.map /FileAlign:0x200

Without work around:
Hello.bin : error LNK2001: unresolved external symbol ___djgpp_stack_top
Hello.bin : error LNK2001: unresolved external symbol ___djgpp_ds_alias
Hello.bin : error LNK2001: unresolved external symbol __crt0_startup_flags
Hello.exe : fatal error LNK1120: 3 unresolved externals

with workaround, linked ok, but SIGSEGV at running:
