# Makefile for VIM on Win32, using Cygnus gcc
# Last updated by Dan Sharp.  Last Change: 2005 Jan 08
#
# This compiles Vim as a Windows application.  If you want Vim to run as a
# Cygwin application use the Makefile (just like on Unix).
#
# GUI		no or yes: set to yes if you want the GUI version (yes)
# PERL		define to path to Perl dir to get Perl support (not defined)
#   PERL_VER	  define to version of Perl being used (56)
#   DYNAMIC_PERL  no or yes: set to yes to load the Perl DLL dynamically (yes)
# PYTHON	define to path to Python dir to get PYTHON support (not defined)
#   PYTHON_VER	    define to version of Python being used (22)
#   DYNAMIC_PYTHON  no or yes: use yes to load the Python DLL dynamically (yes)
# TCL		define to path to TCL dir to get TCL support (not defined)
#   TCL_VER	define to version of TCL being used (83)
#   DYNAMIC_TCL no or yes: use yes to load the TCL DLL dynamically (yes)
# RUBY		define to path to Ruby dir to get Ruby support (not defined)
#   RUBY_VER	define to version of Ruby being used (16)
#   DYNAMIC_RUBY no or yes: use yes to load the Ruby DLL dynamically (yes)
# GETTEXT	no or yes: set to yes for dynamic gettext support (yes)
# ICONV		no or yes: set to yes for dynamic iconv support (yes)
# MBYTE		no or yes: set to yes to include multibyte support (yes)
# IME		no or yes: set to yes to include IME support (yes)
#   DYNAMIC_IME no or yes: set to yes to load imm32.dll dynamically (yes)
# OLE		no or yes: set to yes to make OLE gvim (no)
# DEBUG		no or yes: set to yes if you wish a DEBUGging build (no)
# CPUNR		No longer supported, use ARCH.
# ARCH		i386 through pentium4: select -march argument to compile with (i386)
# USEDLL	no or yes: set to yes to use the Runtime library DLL (no)
#		For USEDLL=yes the cygwin1.dll is required to run Vim.
# POSTSCRIPT	no or yes: set to yes for PostScript printing (no)
# FEATURES	TINY, SMALL, NORMAL, BIG or HUGE (BIG)
# WINVER	Lowest Win32 version to support.  (0x0400)
# CSCOPE	no or yes: to include cscope interface support (yes)
# OPTIMIZE	SPACE, SPEED, or MAXSPEED: set optimization level (MAXSPEED)
# NETBEANS	no or yes: to include netbeans interface support (yes when GUI
#		is yes)
# NBDEBUG 	no or yes: to include netbeans interface debugging support (no)
# XPM		define to path to XPM dir to get XPM image support (not defined)
