*** Please downgrade/upgrade C compiler to version gcc-2.95.x or gcc-3.x! ***

You are not using a supported compiler. We do not have the time to make sure
everything works with compilers other than the ones we use.  Use either the
same compiler as we do, or use --disable-gcc-checking but DO *NOT* REPORT BUGS
unless you can reproduce them after recompiling with a 2.95.x or 3.x version!

Note for gcc 2.96 users: Some versions of this compiler are known to miscompile
mplayer and lame (which is used for mencoder).  If you get compile errors,
first upgrade to the latest 2.96 release (minimum 2.96-85) and try again.
If the problem still exists, try with gcc 3.x (or 2.95.x) *BEFORE* reporting
bugs!

        GCC 2.96 IS NOT AND WILL NOT BE SUPPORTED BY US !

     *** For details please read DOCS/users_against_developers.html ***

******************************************************************************

Hmm. You really want to compile MPlayer with an *UNSUPPORTED* C compiler?
Ok. You know. Do it. Did you already read DOCS/users_against_developers.html???

DO NOT SEND BUGREPORTS OR COMPLAIN, it's *YOUR* compiler's fault!
Get ready for mysterious crashes, no-picture bugs, strange noises... REALLY!
Lame which is used by mencoder produces weird errors, too.

If you have any problem, install a GCC 2.95.x or 3.x version and try again.
If the problem _still_ exists, then read DOCS/bugreports.html !

'config.h' and 'config.mak' contain your configuration options.

'make' will now compile MPlayer and 'make install' will install it.

You have an outdated version of libSDL installed (older than v1.1.7) and SDL
support has therefore been disabled.

Please upgrade to a more recent version (version 1.1.8 and above are known to
work). You may get this library from: http://www.libsdl.org

You need to rerun ./configure and recompile after updating SDL.  If you are
only interested in the libSDL audio drivers, then an older version might work.

Use --enable-sdl to force usage of libSDL.
