Okay, here's a second guess:

----------------------------------------------------------------------------
PKG_CHECK_MODULES([SDL_MIXER],
   [SDL_mixer],
   ,
   [
     [echo "SDL_MIXER not found via pkg_config, checking with AC_CHECK_LIB:"]
     [AC_CHECK_LIB([SDL_mixer],
        [Mix_OpenAudio],
        ,
        [AC_MSG_ERROR([SDL_mixer not found!
http://www.libsdl.org/projects/SDL_mixer])]
     )]
     [echo "SDL_MIXER successfully located"]
   ]
)
----------------------------------------------------------------------------

And here's a third one:

----------------------------------------------------------------------------
PKG_CHECK_MODULES([SDL_MIXER],
   [SDL_mixer],
   ,
     [echo "SDL_MIXER not found via pkg_config, checking with AC_CHECK_LIB:"]
     [AC_CHECK_LIB([SDL_mixer],
        [Mix_OpenAudio],
        ,
        [AC_MSG_ERROR([SDL_mixer not found!
http://www.libsdl.org/projects/SDL_mixer])]
     )]
     [echo "SDL_MIXER successfully located"]
)
----------------------------------------------------------------------------

Indeed, that's really strange.

BTW, a look into the M4 manpages or the Autoconf manpages might help.

Maybe some other quoting or a ";" or similar is needed, or maybe
there is a macro similar to "MSG_WARN" that is a proper replacement
for the "echo" statement.
