Regression from 3.2 to 3.3

[Will Newton <wnewton@cmedltd.com>]

A package I maintain (aqsis) no longer builds with gcc 3.3 as the default 
compiler. The error given is:

shaderstack.h: In function `void Aqsis::OpCAST(A&, B&, Aqsis::IqShaderData*,
   Aqsis::IqShaderData*, Aqsis::CqBitVector&) [with A = TqFloat, B =
   Aqsis::CqColor]':
shadervm1.cpp:277:   instantiated from here

`/home/wnewton/debian/packages/aqsis/test/aqsis-0.7.16/libshadervm'

Can anyone help me figure out what is causing this? It's holding up new 
versions getting into the archive.
