### To add a new directory to the tree, first choose whether it is a target
### or a host dependent tool.  Then put it into the appropriate list
### (library or tools, host or target), doing a dependency sort.  For
### example, gdb requires that byacc (or bison) be built first, so it is in
### the ${host_tools} list after byacc and bison.  


# these libraries are used by various programs built for the host environment

	host_libs="${host_libs} libgui"

# Note, the powerpc-eabi build depends on sim occurring before gdb in order to
# know that we are building the simulator.
