#
# fv makefile for UNIX hosts
#
VERSION=220

#
# Feature options:   (add to OPTIONS line)
#	-DSTRICT_VI
#		Typematic mode at prompt starts in editor state when defined,
#		keys in search functions act more close to vi
#	-DZERO_START
#		'0' takes you to start of file rather than beginning of line
#	-DEMACS_FEEL
#		Give program more of Emacs feel, some compromise to vi feel
#	-DALIGN_VIEW
#		Always align the display address by current cursor size
#	-DSHOW_EXTASCII
#		Display ASCII codes 161-255 in viewer when defined
#		This mode is not appreciated by all terminal types
#	-DEDIT_MEMORY
#		Enable memory edit functions
#	-DCOLON_MODE
#		Enable colon mode prompt
#	-DHUGE_BUFFER
#		Make the search buffer very large for screenless edits
#	-DCOLOR_CURSES
#		Use curses colors for different display regions.  This is
#		not well-tested as color_xterm has curses emulation bugs.
#	-DCURSES_UPDATE_BUG
#		When displaying the screen, force buggy curses (Linux 2.0.29)
#		to redraw screen rather than attempting to just update it.
#
# Target options:   (add to OPTIONS line)
#	-DSolaris1           ** Should be automatically selected
#		If compiling for Solaris 1.x (SunOS 4.x)
#	-DSolaris2           ** Should be automatically selected
#		If compiling for Solaris 2.x (SunOS 5.x)
#	-DFreeBSD           ** Should be automatically selected
#		If compiling for FreeBSD (need different make)
#	-DLinux             ** Should be automatically selected
#		If compiling for Linux
#	-DAmiga             ** Should be automatically selected
#		If compiling for AmigaDOS (no signal support)
#		Amiga does not need -ltermcap with curses from S.J. Raybould
#       Additional options may be -m68040 -m68881
#	-DNetBSD
#		If compiling for NetBSD
#	-DHPUX
#		If compiling for HP/HPUX (need different make or use cmdline)
#	-DDynix
#		If compiling for Dynix/BSD (Sequent - no cbreak mode)
#	-DWin32
#		If compiling for Windows 95 / NT  (use makefile.dos)
#	-DOS9               (use makefile.os9)
#		If compiling for OS-9/OS-9000, must also define HOST_ARCH=OS9
#		Must also add -v=. -to=os9000 and -tp=<TARGET> to CFLAGS line
#		Must also swap $(OBJS) compile comment lines
#	-DLINT	Set if running lint on source (includes lint.h)
#
#
#
# To compile for extended curses key functions (like keypad) on SunOS 4.x:
#	Add -I/usr/5include to CFLAGS and -L/usr/5lib to LDFLAGS, does not work
#	currently due to other SYSV incompatibilities
