+# Compiles in both the LISP code and (the undocumented) chdir
+# command within the editor; take these out of CFLAGS to make some
+# breathing room in the text space if necessary.  If you take out -DLISP
+# you should move ex_vars.nolisp to ex_vars.h
+#
+# If your system expands tabs to 4 spaces you should -DTABS=4 below

+# Ex is likely to overflow the symbol table in your C compiler, so
+# it uses -t0 which is (purportedly) a C compiler with a larger
+# symbol table.  -t1 compiles switches into instructions making larger
+# text, but saving data space.

+# Ex wants stdio only to get the doprnt.o routine; if other stdio stuff
