# Defined SHARED_DATA to be whatever will make your compiler make initialized
# variables shared and read only.  Don't do this on a PDP-11 if you're also
# compiling separate I&D since doing so puts the shared data in text space
# which can't be accessed normally.

#SHARED_DATA=-R

# CFLAGS=-O -Dunix=1 -DFLEXNAMES
# If you don't have split I/D, you'll have to edit the constant
# SBSIZE in cpp.c to reflect this.
