# MPlayer configurator.   (C) 2000 Pontscho/fresh!mindworkz
#				   pontscho@makacs.poliod.hu
#
# Changes in reversed order:
#
# 2001/06/04 by Nick Kurshev
# - added hard checking of gcc and soft of assembler
#
# 2001/05/40 by LGB
#  - added --prefix support
#
# 2001/05/22 by Nick Kurshev
#  - added definition of CPU clone
#
# 2001/04/16 by LGB
#  - added libcss stuffs
#
# 2001/04/15 by Pontscho
#  - added --disable-select option
#  - added X11DIR variable in config.mak and fix syncfb Makefile -L/usr/X11/lib bug 
#
# 2001/03/24 by Mike Graffam:
#  - added autodetect code for XF86VidMode, along with explicit --enable-vm
#
# 2001/03/22 by Bivanbi:
#  - new option: --cc  (to specify C compiler path+name)
#
# 2001/03/08 by LGB:
#  - DGA detect-o-matic :)
#  - '--disable-dga' option to force disabling DGA vo driver compiling into mplayer
#  - line about '--enable-dga' is added to the help message
#
# 2001/02/26 by A'rpi:
#  - added DGA option:  --enable-dga
#  - no notify if --with-win32libdir used [Tibcu]
#
# 2001/02/25 by LGB:
#  - TMPDIR or TEMPDIR variable is honored during tests for temporary files
#  - ChangeLog inside configure was reversed ;-)
#
# some changes by A'rpi/ESP-team:
#  - added 'athlon' target for the new athlongcc [Ian Kumlien]
#  - applied _win32libdir=-L patch by Magnus Pfeffer
#
# some changes by LGB:
#  - Ehhh, AMD K6-2 returns with cpuid 5 ;-) Changing back Arpi's last change :)
#    More info: AMD K6-2 reports with family 5, duron with 6, so I attached
#    much finer CPU type detection based on Linux kernel's one :)
#    (k5: 5, model<6, k6: 5, model>=6, k7: 6, model=any)
#  - On some exit point (error) temporary files were not deleted. Fixed.
#  - $TMP and $TMP2 are renamed to $TMPC and $TMPO ;-)
#  - Some useless { ... } are removed
#
# some changes by A'rpi/ESP-team:
#  - the --with-win32libdir patch by Aaron Hope applied
#  - some english bugfix again :)
#  - cpu type selection changed:
#    ( k7->k6->k5-> ) || (i686->pentiumpro-> ) pentium-> i486 -> i386 -> error!
#  - cpu type for AMD/family=5 changed k6->k5
#
# some changes by LGB (G<>bor L<>n<EFBFBD>rt):
#  - SOME gcc may support 'k7', so I added tests for ALL CPU type optimization
#    switches with the ability to find out the best optimization for your CPU.
#  - Help moved to the begining to avoid tests if user only wants help.
#  - A one lined help to indicate detailed help for users
#  - Fixed /tmp race (PIDs can be predicted, I added random numbers as well)
#
# some changes by A'rpi/ESP-team:
#  - some english bugfix :)
#  - removed _??exists flags, _?? is enough...
#  - creating only config.mak files instead of whole Makefiles
#
