VxWorks 5.5.2, 6.8 and 6.9 all have close() defined in unistd.h. In the
VxWorks 6.x versions this header comment shows when they did that:

02w,31aug06,mwv  move kernel definitions of read(),write(),close() 
                 to unistd.h (WIND00038902)

My Jenkins builds against 6.8 and 6.9 have not failed.

Dirk, which VxWorks version is this failing against? Do you have any
other local changes that are needed to support EPICS 7 on that version?
