Test case for differences in GCC 3.4.3 and 3.3.4 template expression code gen
Compile to assembler (e.g. g++ -S -O) using same flags with both a GCC 3.3
series compiler, and a GCC 3.4 series compiler and spot the file length
difference - you MUST use an optimisation flag for it to compile correctly
(another bug, already submitted.)
