##	HERE ARE SOME USER-CONFIGURABLE VARIABLES

EXTRA_CFLAGS="$CFLAGS -DUNIT_ON_MAP -DNEW_AI -DUSE_LIBMODPLUG -DUSE_HP_FOR_XP"
EXTRA_LDFLAGS="$LDFLAGS"

## These could be used for experimental versions
## ---------------------------------------------
## SLOW_INPUT		If you have problems that events aren't fetched.
## BPP8_*               Only for X11 8bpp common palette:
##   BPP8_NORMAL          disables default, like other Xbpp (delivers errors)
##   BPP8_WINSAFE         Uses a windows safe palette instead.
##   BPP8_IRGB            Uses a palette based on 4x4x4 RGB in 4 intensities
## There are some still not well tested code parts or branches.
## UNIT_ON_MAP		Fast lookup of units
## UNITS_ON_MAP		Faster lookup of units
## NEW_AI		New better improved AI code
## USE_TILECACHE	Faster tile drawing, costs memory.
## USE_SMART_TILECACHE	Faster tile drawing, slow with hardware video memory.
## USE_HP_FOR_XP	Use hit-points for XP calculations.
## USE_LIBMODPLUG	Use modplug audio player support.
## USE_FLAC		Use flac audio player support (asked by setup).
## USE_OGG		Use ogg audio player support (asked by setup).
## USE_MAD		Use mad mp3 audio player support (asked by setup).
## These aren't working yet:
## NEW_MAPDRAW		Stephans new map draw code (value>1 shows update)
## USE_FFMPEG		Use ffmpeg video player support.
## NEW_FOW		New fog of war code, should work correct
## NEW_SHIPS		New correct ship movement.
## HIERARCHIC_PATHFINDER	Use hierarchic pathfinder
## USE_LUA		Lua scripting support

##-----------------------------------------------------------------------------

# if your system/distribution lacks libpng, you may install the source
