*** 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/HTML/en/users-vs-dev.html ***

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

Hmm. You really want to compile MPlayer with an *UNSUPPORTED* C compiler?
Ok. You know. Do it. Did you read DOCS/HTML/en/users-vs-dev.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/HTML/en/bugreports.html !
