Hi, 
the compilation of kdemultimedia-3.0.1.20020604 fails with the following 
errors (on gentoo 1.3a)

This is actually a bug in mpeglibs assambler code triggered by gcc3's -O3
optimization. Inlining global identifiers is just a bad idea.

Fix: Compile it with -O2 to avoid inlining, not with -03.

BTW: This issue is already fixed in KDE's CVS and thus will go away with the
next KDE release.

Cheers.

Since there are newer versions of this package that works I guess this bug is no
longer relevant.
