Why do KDE packages depend on gcc-3.2?

[Jeff Tranter <jefft@xandros.com>]

I'm curious why the KDE 3.1 Debian packages have a build dependency on 
g++-3.2 when they build just fine with older versions of g++? Is it just 
to make sure no one runs them on a system with the older compiler? For 
those of us building packages on a system based on Debian Woody, the 
dependency is just a minor annoyance.
