I may be confused here. Are we talking about DJGPP's stock `ld'? For me
(Binutils 2.7), if the linker reports an unresolved external when creating
an executable, it halts the linking and does not actually create the
executable. I browsed the docs and did not see any option to make it a
warning instead and continue the link.

Of course, if you link with `-r', it won't even report them, since it's not
a problem.
