As pl stated in his mail, the lame-coders changed the relevant part of
the doku concerning the differences. So, compiling lame with the options
configure guesses for your system should be ok and not the source of
your problems, if, of course, if you don't use gcc-2.97minus1, which indeed
can cause some very strange obscurances in combination with lame.

Grab the latest CVS from lame, compile, and recompile mplayer/menconder
against those new libs. Be sure you have no cruft, like old header-files
from previous lame installations lying around and confusing both
configure and your compiler.
