# You may have to change the following sets of macro definitions which will
# be used throughout the build makefile. These definitions cover the paths
# to look into for the operating system and networking header files, and
# the names and parameters passed to the program which actually do the
# compilation, library building and cleanup work.
#
# Note that for either set you still need the GNU make utility to build the
# library!
# These are for the cross compiler, with the operating system header files
# stored in "/V/include" and the network header files in a local directory
# called "netinclude".
