/FORCE (Force File Output)
The /FORCE option tells the linker to create a valid .exe file or DLL even if a symbol is referenced but not defined or is multiply defined.
The /FORCE option can take an optional argument:
Use /FORCE:MULTIPLE to create an output file whether or not LINK finds more than one definition for a symbol.
Use /FORCE:UNRESOLVED to create an output file whether or not LINK finds an undefined symbol. /FORCE:UNRESOLVED is ignored if the entry point symbol is unresolved.
/FORCE with no arguments implies both multiple and unresolved.
A file created with this option may not run as expected. The linker will not link incrementally when the /FORCE option is specified.
If a module is compiled with /clr, /FORCE will not create an image.
