[dev] Problem building dmenu tip

I'm having the following problem when building dmenu tip on OpenBSD
current. At first I thought it was a problem with OpenBSD, but a user
in the irc channel said he remembers a similar problem when linking with
ld on Linux. Any ideas?

dmenu build options:
CFLAGS = -std=c99 -pedantic -Wall -Os -I. -I/usr/include -I/usr/local/include -I/usr/X11R6/include -D_BSD_SOURCE -DVERSION="4.1.1"
LDFLAGS = -s -L/usr/lib -L/usr/local/lib -lc -L/usr/X11R6/lib -lX11 -ldraw
CC = cc
