gcc (GCC) 3.4.2 [FreeBSD] 20040728
	
>Description:

kdemultimedia3 doesn't build under GCC 3.4.2 (when "-O2" is used) because a
Linuxism was used to detect the version of GCC.  The attached patch fixes the
problem by using the equivalent FreeBSD macro.

>How-To-Repeat:

Try building kdemultimedia3 using GCC 3.4.2 and CFLAGS="-O2 -pipe".
WITH_MPEGLIB must also be enabled.
