# If you are compiling this for a nonseparate I/D machine,
# you must:
#	change the definitions of LDFLAGS, CFLAGS, LIBES,
#	SIGRETROSRC, and SIGRETROOBJ
#	make Mail40 rather than Mail
#
# Mail is too large to fit on a nonseparate I/D machine without
# text overlays.
#
# If you do not have a vfork system call or do not support
# job control, you must change the definition of OPTIONS.
