: In trying to compile driver code which includes unistd.h, the compiler
: complains:

#include <unistd.h>

isn't supported for drivers.  You should not be including the
-I/usr/include on the command line to compile the driver.  If you are
building a module, you should be using the bsd.kmod.mk framework to
build the modules.  include <sys/unistd.h> instead.

You will also need to create an opt_posix.h in your driver's Makefile:

KMOD=ifx
SRCS=ifx.c device_if.h bus_if.h opt_posix.h

.include <bsd.kmod.mk>

should be all you need.  You may also need to define SYSDIR as well if
you don't have it installed in /usr/src/sys.
