no line numbers in backtraces on Mac OS X?

Hi,

Is it normal that there are no source line numbers in backtraces on Mac OS?
Despite many patches to winedbg etc., the backtraces I get are
no better that those from 1.1.24 times.
  18 0x41f5b2a1 _OpenDriverA+0x51() in winmm (0x0032ce78)
  19 0x4041467f _initAudioDlg+0x75f() in winecfg (0x0032dc28)

I'm using configure + make to build.  On Linux, the line numbers help
a lot in locating bogus code.

Thank for your help,
    Jörg Höhle.
