Sorry, I simply don't understand that. The build completes with -O2 but not
with -O3. I'm light years away from even a basic knowledge of compiler
technology, but I would have thought that if the compiler inlined something,
there would be no reference for the linker to subsequently resolve. But, like I
say, I'm light years...

Anyway, since filing the bug report, I've built the package on my laptop, which
has GCC 3.3.6 installed. In this case the build completes with -O3
optimisation.

If I was a C++ programmer, I might just do that. Unfortunately, I'm not! I did
have a dabble with Borland C++ many years ago, but since then templates (and
similar stuff) have been introduced and made the language too complex for me to
be bothered..

That was my first port of call, but I got no response.
