I am having problems with the getminor() call.  I am making some calls
to getminor() in order to extract the minor numbers, according to the
ddi/dki ref manual:


#define  dev_to_cont(dev)  (ushort)(((getminor((dev_t)dev))>>10)&3)

void
sdsgopen(dev_t *dev, int flag, int otyp, cred_t *cred_p)

{
        ushort                  controller      =       dev_to_cont(dev);


I am including the appropriate include files (ddi.h is last) and this
should work, but when I do an idbuild, I get the following errors:


camber:/home/det/src/sdsg$ make install
        if /etc/conf/bin/idcheck -p sdsg; then /etc/conf/bin/idinstall -a sdsg;
else /etc/conf/bin/idinstall -k -u sdsg; fi
        /etc/conf/bin/idbuild

        The UNIX Operating System will now be rebuilt.
        This will take some time.  Please wait.

	Did you miss to include <sys/sysmacros.h> ?
	All the listed undefined are there.
