# SGI linker has some peculiar requirements on the order in which share
# libraries are specified on the command line.
#    1. Two libraries cross reference each other, as it is the case with 
#       -lomniORB4 and -ltcpwrapGK means that -lomniORB4 has to be
#       repeated after -ltcpwrapGK
#    2. Multi-threaded programs must have -lpthread as the last option
#       on the command line.
# To satisify #2, we arrange in OMNIORB_LIB that -lpthread is the last
# option. So as long as in a dir.mk, the $(CORBA_LIB) is the last one
# in the assignment to libs, this condition is satisfied. 
# E.g.
#      $(eg1): eg1.o $(CORBA_STUB_OBJS) $(CORBA_LIB_DEPEND)
#        @(libs="$(CORBA_LIB)"; $(CXXExecutable))
#

# Here we reset the value of OMNIORB_LIB to meet the above requirements. The
# variable was original set in unix.mk
