# CFLAGS = -g -DUSG
# LIBS = -lPW
# INSTALL = cp
# (If you compile with GCC, you don't need to define LIBS.)
# And, depending on the names and contents of your header files,
# add either -DHAVE_NDIR or -DHAVE_DIRECT or both to CFLAGS.
# Add -DHAVE_NDIR to CFLAGS if your system used ndir.h instead of dirent.h
# Add -DHAVE_DIRECT to CFLAGS if your system uses 'struct direct' instead of
# 'struct dirent' (this is the case at least with one add-on ndir library).
