windows media player really wont accept a standard mp3 file???

That is the right place, but it looks like an old version. The code
in the #else is never used and has been deleted.
In the ISO code and older versions of lame, empty_buffer is only
called if the buffer is full. So tmpbuf will always contain
several frames. In newer versions, LAME was modified to
call empty_buffer() after encoding every frame, and
lame_encode() will return a copy of tmpbuf after encoding
every frame. But sometimes this will be empty, and on rare
occasions it can have more than one mp3 frame.
